The pair are assigned to patrol Sector D, until two guards send them on all alternate mission. Sebastian wants Daryl and Rosita to cover themselves in walker guts, and travel through a herd, to find money that an old friend's father had locked away. They both quickly refuse, until Sebastian threatens R.J. and Coco. Rosita holds him at gunpoint, while his guards aim at her and Daryl. They assure them that they will fire, in which Rosita responds "Not before I take this asshole's head off." Rosita agrees to do the mission, as long as it's the last thing Sebastian makes them do.
Once in the house, they find the panic room where the money is obtained. Rosita kills two walkers, and notices that they recently turned, meaning someone has sent citizens to do this before. Out of nowhere, a woman begins banging from inside the room, alerting the attention of Rosita and Daryl. She states her name is April, and she was part of a previous group who came to complete this mission. In response, Rosita tells her, her name and assures her that they're going to get her out of there.
Once Daryl starts the generator, Rosita enters the code, unlocking the panic room, where she is embraced in a hug from the woman inside. An alarm system begins to sound, so Rosita attempts to cut the wires to turn it off. Walkers begin to be attracted to the noise, so she goes for the quicker solution of smashing it with her helmet.

After the altercation, April has been mutilated, causing Rosita to put her down before she can reanimate. They complete the mission successfully, with Mercer telling them to give the money to Sebastian, because if they don't, that's a fight they're not going to win.

- "Trust"
Rosita confides in Eugene about what happened during Sebastian's money heist. Doing so, they arrange a meeting with Connie and Kelly. She explains how Sebastian forced many citizens to complete this mission, in which none have made it out alive, April included. Connie shows her the list of names she received days prior, revealing April to be on there. Rosita claims that there are far more people on the list than Sebastian sent in, so something else must be going on and the citizens of the Commonwealth deserve to know the truth.
- "Lockdown"
Rosita first appears in the crowd, alongside Connie, Kelly, Magna and Ezekiel, during a protest against Sebastian Milton. She tells the group that they can't make a decision on what to do, until everyone is back. Mercer approaches her and questions why she isn't in uniform.

Later in the episode, Rosita is geared up and ready to take on the herd. Mercer jokes about her showing up, in which she responds "I heard walkers needed killing, I couldn't resist." The pair drive off, reaching an open field where a horde of walkers are roaming.
Mercer and Rosita have a heart to heart, in which he tells her he needs people like her on the force, people he can trust. She assures him that if he needs help outside the walls, taking on walkers, she will, but anything that goes on inside, she doesn't want any part of it, as her daughter and family come first. Mercer says he respects that and assures her that if she ever needs help getting her family out, he will.

In the following episode "Variant", it is revealed that Rosita also spent some time at the Founders Day parade with Eugene.
- "Variant"
We first see Rosita being escorted from her apartment by three armed soldiers, in response to Eugene's actions at the Founders Day parade. She is taken to a small room, where she is interrogated by Mercer. He demands to know where Eugene is, and lays out the trouble her and the rest of the group will be in, if he isn't found. Rosita is offended that Mercer is treating her like a stranger, after the conversations they had just a few days prior, and claims she has no idea of Eugene's whereabouts.
As Daryl and Eugene hold up in Gabriel's church, we hear a knock on the door. Daryl pulls his knives out, ready to take on any potential threat, but it's Rosita - revealing she had just lied to Mercer, to protect Eugene. They begin preparing to pack their things, working out a plan on how to escape, when Eugene informs them he will not be leaving without Max. Seeing how adamant he is, Rosita makes a deal with Eugene, that if she can go find her and bring her back, they might be able to sneak them both out. Eugene agrees.
Later in the episode, we see Rosita finds Max hiding down a small alley. As Max runs towards her, Rosita notices two guards are near-by, so she quickly ushers her to go back into her hiding spot. Unfortunately, another two guards were approaching from the opposite direction, causing Max to be arrested & taken into police custody.
Rosita returns to the church and tells Eugene the news. In his heartbreak, he informs her and Daryl that he has decided to hand himself in. You can clearly see the hurt on Rosita's face, leading Daryl to leave the room, allowing the pair one final conversation. Eugene tells Rosita that there's no life living without Max, and she was the one who told him that his person was out there. In a conversation filled with hugs and tears, Eugene hands Rosita his bolo tie, requesting she gives it to Coco when she's older.
The episode ends with Rosita in her apartment looking at the bolo tie. She lets out a small smile, but its clear to see that she is hurting with what has just happened. As a door opens in the background, Rosita grabs her bag, assuming the group has arrived and ready to leave. She walks into the living room, when all of a sudden she is hit over the head, revealing two men have been sent to her apartment, in an attempt to kidnap her. She fights back, kicking and punching, but is quickly overpowered. A bag is placed over her head, as the episode cuts too black.
- "Outpost 22"
In the back of one of the Commonwealth transport trucks, Maggie wakes up and shakes off her hood, finding Gabriel and Rosita with her and their guard asleep. Maggie remembers being forcefully separated from Hershel when the Commonwealth soldiers had abducted them. Maggie manages to break free of her zip ties and quietly wakes up Gabriel. Unscrewing a piece of metal from the wall, Maggie cuts Gabriel loose who frees Rosita. Rosita and Gabriel jump from the back of the moving truck, but the guard wakes up before Maggie can escape as well and the two struggle over his gun. The gun goes off in the fight, accidentally killing the truck's driver. Finally, Maggie throws the soldier from the back of the truck just before it crashes into a tree. Climbing out, Maggie finds the passenger dead, having been flung from the truck and into the tree by the impact. Maggie attempts to take the driver's gun, but she is forced to flee into the woods as the rest of the Commonwealth convoy approaches.
The next morning, as Gabriel and Rosita lie unconscious in the road, their former guard, now a walker, approaches Rosita who wakes up just in time. Gabriel draws the walker's attention towards him and yanks his helmet off, giving Rosita the chance to grab the soldier's machete and impale him in the head with it, putting him down. The two quickly begin scavenging the body for his weapons and radio while Gabriel notices that Rosita was injured in the fall from the truck, although she brushes off his concerns. Over the soldier's radio, a soldier from Outpost 41 reports that there's no sign of the dead soldier or the escapees. Another soldier reports in that he has found a set of boot tracks that might be from the dead soldier. Realizing the danger, the two take off down the road before the Commonwealth forces can find them.
Rosita and Gabriel reach the road and Rosita begins following the tracks of the Commonwealth convoy. Gabriel calls for her to hold up, and asks what their plan is. Rosita intends to follow the convoy wherever it goes, but Gabriel points out the foolishness of that plan as there are only just two of them. However, Gabriel doesn't have a better idea and Rosita suggests splitting up in order to cover more ground, but Gabriel refuses to leave her. Two walkers emerge from the woods and Gabriel quickly puts one down, but Rosita suddenly collapses in pain when the other walker attacks her. Gabriel saves her, and Rosita reveals that her arm is dislocated, and that she needs Gabriel's help to pop it back into place. Gabriel fixes Rosita's arm, but she insists on pressing on rather than resting, blaming herself for Coco being taken. Gabriel tells Rosita not to torture herself and reminds Rosita of her own words when Gabriel beats himself up: "quit bitching and move forward." As Rosita finally calms down, the two are surprised to hear a train whistle in the distance as there are no trains anymore.
At Junction 7, Rosita and Gabriel join the Maggie and Carol, explaining that they'd heard a train and followed it. Inside, Daryl lowers Nelson to the ground against a wall and checks his wound. Recognizing that it's mortal, Daryl tells Nelson that he's running out of time, and he asks the other man to do something good with the time that he has left and tell him where the train is going and what Designation 2 means as one of Daryl's friends was put on it with that designation. Coughing up blood and in pain, Nelson doesn't respond to Daryl's questions. Daryl tells Nelson that he was like him once: he joined the force because his family needed money which Daryl guesses is Nelson's motivation as well. Turning violent when Nelson continues to remain silent, Daryl yells that the Commonwealth has taken his kids from him and he wants them back, going so far as to kick the dying man. Entering, Carol tells Daryl that the train is going to be here soon, and Daryl suggests that they can hurry, drawing his knife and he offers Nelson the choice of dying quick or screaming.
Gabriel recognizes Nelson as a man from his church who was there every Sunday at the back pew closest to the door. Nelson would always come a little late and leave a little early, and it had seemed like Nelson had wanted to talk about something. Nelson asks if God forgives people like him, but Gabriel doesn't know, although he wishes that he did. Nelson admits that he's torn up all of the time with guilt and shame. Gabriel states that it's because Nelson's a coward, but that's alright as he's trying not to be. Gabriel knows that fear can drive people to do things that bring shame, but it can also push them into the light. Nelson is trying to do the right thing now which God sees and so does everyone else. Nelson tearfully wishes that he'd talked to Gabriel sooner which Gabriel wishes too. Nelson coughs up blood and Daryl nods to Gabriel who tells Nelson that "people remember the last thing that you do. The end of each story is very important. How do you want yours to end?" Nelson finally reveals that the Commonwealth punishes exiles by making them do hard labor and their friends are on railway duty. However, Nelson doesn't know where as he was only called out when they escaped, and they have to follow the train to find their friends. Addressing Daryl, Nelson states that he's only heard rumors about Designation 2 with the rumors stating that the Designation 2s are taken far away and they are never seen again. Daryl leaves and Gabriel agrees to pray with Nelson while he goes. Carol leaves at Gabriel's request and he sits down and prays with the dying man.
A few minutes later, Gabriel emerges carrying a bloody knife, having stabbed Nelson in the head to keep him from reanimating after he died. Daryl tells his friends that Connie's gone if the train pulls in, but Rosita worries that if the train sees them coming, they're going to radio ahead and the best way for them to get the kids is for the Commonwealth to not know they're coming. Daryl refuses to just leave Connie on the train and Carol tells him that she has an idea about how to do both.
The train arrives at the junction where Trooper 192 emerges and puts down a walker before trying to move the junction switch which is stuck. Wilson attempts to let Outpost 22 know that they have a stuck junction switch and that it will take a few minutes to dislodge it, but he receives no response as Trooper 192 puts down another walker that emerges from the woods. Entering the cab, Maggie orders Wilson to put down the radio at gunpoint. Daryl and Carol sneak along the side of the train, putting down an approaching walker before ducking as an annoyed Jones asks his fellow soldier how hard it can be and Trooper 192 challenges him to come over so he can show Jones. Spotting a herd emerging from the woods and coming down the tracks, Jones orders Trooper 301 and Trooper 263 to cover the woods and the flank respectively.
Daryl and Carol crawl under the train as Jones jumps off the side, puts down a walker and goes to join Trooper 192 at the junction switch. In the woods, Trooper 301 finishes clearing the woods of walkers and calls in that the woods are cleared and she's heading back. Rosita and Gabriel ambush the soldier, disarming and killing her quietly so as not to draw notice from the other soldiers. Jones attempts to move the junction switch without success, and takes a closer look, realizing that someone had purposefully jammed it.
Alarmed, Jones orders everyone to get back there now, but Daryl opens fire before anyone can respond, killing Trooper 263. As Daryl and Carol take cover on the train, Jones and Trooper 192 each come down one side of the train, engaging in a gunfight with Daryl and Carol. Maggie emerges from the train cab and shoots Trooper 192 dead from behind. Daryl proceeds down the side, only to have Jones emerge with Connie as a hostage. Jones forces Daryl to disarm himself and, after Daryl admits that they had disabled the train's long-range antenna, Jones demands to know exactly what they did to it. While the soldier is distracted by Daryl, Connie breaks free and Jones takes off running through the train, chased by Daryl after he makes sure that Connie's alright. Jones takes one of the motorcycles being transported on the train and flees while Carol helps Connie to her feet. Leaving his friends to deal with the approaching herd, Daryl takes the other motorcycle and chases after Jones who crashes his motorcycle after going off-road with it in an attempt to avoid Daryl. Sliding his motorcycle under a fallen tree, Daryl hits Jones, sending him to the ground and knocking the man's helmet off. Daryl stabs Jones in the head, killing him.
Carol, Maggie, Gabriel and Rosita lead Wilson into the building where he refuses to help, stating that he's dead if he helps them. Wilson is shocked to see Nelson's dead body and Maggie warns the man that he's dead if he doesn't help them. Wilson explains that his family lives at a nearby outpost and if the Warden finds out that he helped them, Wilson will end up just like their friends. Rosita explains that the Commonwealth took their children and asks about the family that Wilson had mentioned before suggesting that Nelson had a family too. After a moment, Wilson tells them that there's a map in the train's engine room. Maggie and Carol take Wilson to get the map. Daryl returns and reunites with Connie, admitting in sign language that he was afraid that he wasn't going to see her again. Connie reassures Daryl that she's not going anywhere, causing Daryl to chuckle.
Suddenly, Daryl and Connie hear the sound of Wilson shouting at Maggie and Carol and rush over to see him holding a tool to his own throat while the two women try to talk him down. Wilson is terrified that the Warden will kill his wife and two sons if he helps them. Carol offers that if Wilson helps them, they will injure him, nothing serious, just enough to make it look like the engineer had barely gotten away from them and Wilson can tell the Warden that he escaped. However, Wilson believes that the Warden will know that he lied, torture him once he does and then kill Wilson's family. Despite Carol's efforts to talk him down, Wilson drives the tool through his neck, killing himself in order to spare his family from the Warden's vengeance.
Connie asks Daryl if they don't know which way to go which he confirms. Connie knows that Kelly is at Outpost 22 and scared and Connie can't lose her. Daryl promises Connie that they will find Kelly and Rosita suggests getting the train's long-range radio working again. Agreeing with the plan, the group heads back to the train to get the radio working again.
At night, posing as Trooper 301, Rosita radios in to Outpost 22, claiming that the train was overtaken and she's lost in the woods with the group still looking for her and she needs to get back to the site. Finally, a friendly soldier responds and Rosita identifies her location as Junction 7, stating that she's the last one left. The woman begins giving Rosita direction from Junction 7 to Outpost 22. The soldier informs Rosita that they don't have any spare units to send out her way for a pickup as they have a convoy coming in for colonial processing on Pamela's orders. "Word is that most of the processees used to live here before the Commonwealth claimed the territory and turned it into an outpost, back when it was still called Alexandria." The soldier tells Rosita that the Warden will debrief her when she arrives and to shoot to kill if she has to engage any hostiles. The group is stunned by the revelation that Outpost 22 is actually Alexandria and Daryl informs Connie of this development. "Milton has underestimated us since day one. We are gonna get our kids, take back our home, and make it right. And Pamela is never gonna see it coming," Maggie declares to her friends who are filled with new determination.
- "Faith"
Outside of Alexandria, Daryl reports that the situation is really bad and he's not sure that any of their friends are going to make it. Gabriel asks if they saw everyone and Carol clarifies that they only saw the adults and that there was no sign of Coco, Hershel and the other kids. Both Maggie and Rosita are concerned by this with Rosita wanting to go in immediately. Daryl, acting as Connie's sign language interpreter so that she understands their conversation, tells the others that they can't go in as there are too many guards and they'll never make it. Gabriel is furious that Pamela had turned their home into a prison after promising to give it back, but Maggie realizes that Pamela had never actually intended to give it back. Daryl comes up with the idea of going in through the sewers and Connie volunteers to go with him while Carol knows a way back into their old house, but she needs some backup just in case the guards blocked it. Maggie decides to go with Carol and Daryl orders them to head for the windmill where a sewer grate is. Rosita wants to go with them too, refusing to stay outside while Coco is inside, but Carol reminds Rosita that she and Gabriel are their best sharpshooters if it comes to that. Carol promises to keep in touch in case something goes wrong, and Rosita reluctantly agrees, although she will come in if takes more than a night. Daryl hands Gabriel his gun and the group separates to enact their plan.
After the successful prisoner rebellion and retaking of Alexandria, Rosita rushes in looking for her daughter who they can't find despite checking all of the other houses. However, Coco isn't with Hershel, and he doesn't know where she is.
In front of the windmill, Negan prepares to kill the Warden with a rock, but he's stopped by Rosita. Rosita demands to know where her daughter is, but the Warden refuses to answer. Seeing Sanborn reanimate, Rosita grabs him and holds the walker over the Warden's face, once again demanding to know where her daughter is. With a smile, the Warden sad*stically tells Rosita that she will lose everything, and Rosita furiously shoves the zombified Sanborn into the Warden's face which Sanborn begins devouring, killing the Warden. Rosita walks away, leaving Sanborn to eat the Warden as her friends, the soldiers and former prisoners watch in shock and horror at the brutal death.
- "Family"
In a reclaimed Alexandria, the Coalition recover their various weapons from a large crate full of weapons confiscated by the Commonwealth.
In front of the windmill, Rosita passes the corpses of Sanborn and the Warden, grabbing an extra clip for her gun off of Sanborn's belt. Gabriel asks Tyler Davis if there's anything that he knows that can help them find the missing children and Tyler reveals that, when he was a soldier, kids without parents would end up at the Commonwealth Children's Home. However, Tyler doesn't know where it is, so he goes to get the location from the captured Commonwealth soldiers at Gabriel's request. Rosita impatiently calls for the Coalition soldiers and freed prisoners to board the Commonwealth's transport bus. Princess asks Magna if anyone actually knows how to drive a train, but Magna reassures her that one of the prisoners apparently used to be an engineer before they board the bus, with Kelly, Connie, Adrienne and Dianne amongst those joining them.
As Maggie loads the back of the bus, Negan asks how she plans to take out Pamela Milton. Negan gets that others have their own reasons for going back to the Commonwealth, but as far as he's concerned, none of them are safe as long as Pamela's still alive which he guesses that Maggie agrees with. Negan suggests that they can take out Pamela together without the help of the others, but Maggie closes the bus door and walks away, telling Negan that "we're not a we." In front of the bus, Maggie hugs Hershel and says a tearful goodbye to her son. Annie hugs Negan from behind and orders her husband to be careful. Negan states that he always is, and Annie tells Negan to come back in one piece while she holds down the fort in Alexandria and Negan promises to do so.
Nearby, Ezekiel says goodbye to Nabila, Aliyah and Gracie while Daryl promises R.J. that they will be back soon and orders him to look after Judith. However, Judith tells Daryl and Carol that she's coming too over Daryl's objections. Judith reminds her friends that this isn't the future that Carl wanted and it's not what Rick and Michonne fought for, not yet at least. What they're doing could help everyone, maybe everybody everywhere, not just them. Judith wants to be a part of making what her family believed in real. Carol recognizes that while everyone else has been focused on the present for a long time, Judith has been thinking about the future which is a good thing and something that they could all do a little more of. Daryl agrees on the condition that Judith stays right with him, and he leaves R.J. in Nabila's care while they're gone.
On the railroad tracks, the Commonwealth's train smashes a walker to bits. Inside, observed by Daryl, Carol, Maggie and Judith, Rosita pours over a map of the Commonwealth with Gabriel, telling him that once they get inside, they will move the former prisoners into hiding and, as they hopefully get Mercer on their side to take out Pamela, she and Gabriel will go to get Coco back. Gabriel notices that they're going in through the lower ward and wonders why they're not going in through the Estates instead. Rosita points out that with more money, the Estates have more patrols, meaning that they don't stand out as much in the lower wards. They're going to use an access road that will allow them to hit the children's home from behind. Gabriel smiles at Rosita and promises her that they will get Coco back which is his faith in Rosita talking and Rosita is glad that Gabriel is with her.
Outside of the tunnel entrance, four Commonwealth soldiers patrol while the Coalition forces hide nearby. Negan tells the others that they are sitting ducks and Mercer isn't coming and they can't wait for him. Carol agrees that it's time for a new plan, but Princess is sure that Mercer is gonna show up. Daryl states that they're running out of time and Carol decides to head around and try to find another way to slip in. Maggie suggests that they could take the four guards, but Rosita warns her that if those guards go missing, the clock is going to start ticking on them. Judith draws the others attention as one of the guards notices something and starts heading their way. However, Lieutenant Rose calls in with orders from Mercer for the guards to report to the East Gate immediately to deal with the incoming herd. Lieutenant Rose confirms that that includes Tunnel H and he reassures the soldiers that the tunnel is locked, and they've got it covered on the other end. Complying with his orders, the guards move out. Breaking the lock on the door, the group makes their way into the tunnel.
The Coalition forces emerge from the tunnel in the seemingly-abandoned Union Station. Daryl quickly deduces that something isn't right, and he notices that the outer doors are all chained shut. Realizing that it's a trap, Daryl yells for everyone to get down as Pamela's private forces, situated on the station's balcony, open fire, killing Tyler and two former prisoners standing near him as everyone else dives for cover.
A gunfight erupts between Pamela's forces and the Coalition with Rosita desperately trying to get the doors open. One Alexandria resident crawls towards a hiding Connie, Kelly, Magna and Dianne, but he is shot in the head and killed by one of Pamela's men before he can reach them. As the gunfight continues, Pamela herself emerges and grabs a gun from one of her men who is killed by the Coalition. Pamela takes aim at Maggie, but Judith notices and shoves Maggie out of the way just in time, saving her life. Instead, Pamela accidentally shoots Judith, seriously wounding the young girl. Daryl desperately attends to Judith as Pamela watches in horror and the others increase their fire, killing a few more of Pamela's men. Yelling that "you did this," Pamela retreats to her office. Looking for a way out, Daryl spots a fire extinguisher near Ezekiel and signals him to throw it. Grabbing Rick's Colt Python from Judith, Daryl shoots the fire extinguisher, creating a smokescreen.
In Union Square, Yumiko and Max observe the heavily guarded doors to Union Station from across the street. Hearing twigs snapping, Yumiko spots a hooded Eugene sneaking around a train car, armed with Brooks' rifle and she tells Max that they are going to go around. Inside, under cover of the smokescreen, Daryl and the others manage to break the chains sealing a side door. As a trooper approaches the doors, Eugene ambushes him and knocks the man out with the butt of his rifle. Magna finally breaks through the doors, and everyone is reunited with Eugene, Yumiko and Max before quickly making their escape.
The Coalition races through the streets towards the hospital with Daryl carrying the unconscious Judith. Commonwealth vehicles drive up and block their path in multiple directions, forcing them to fall back. Carol realizes that the soldiers aren't following them as they begin to erect barricades in the streets. Loudly yelling and firing their guns in the air, Commonwealth soldiers lead the herd in their direction before closing the barricades, penning the herd and the Coalition in. Spotting a walker climbing over something, a shocked Negan asks "what the f*ck?" As walkers close in from multiple directions, Luke and Jules emerge from the herd, causing Kelly to nearly shoot them before Connie stops her sister. Fleeing down a side street, Carol spots an alley near part of the herd and everyone attacks the walkers, clearing a path for Daryl to flee down the alley towards the hospital with Judith. Waking up for a moment, Judith calls out "daddy?" and witnesses her friends and loved ones struggling to hold back the herd before passing out again.
- "Rest in Peace"
In the streets, the Coalition desperately fights off the herd as they try to escape from the walkers swarming around them, those armed with guns shooting the undead while the rest stab at them with knives, including Max. However, Jules misses the head of one walker, instead stabbing it in the shoulder. The walker bites Jules in the arm and Luke rushes to his girlfriend's aid, stabbing the walker in the head and yelling for help as he supports Jules. However, walkers swarm the couple from behind with one tackling Luke to the ground and biting him in the leg as Jules is dragged down and devoured. Seeing Luke's predicament, Connie shoots the walker in the head and Luke is dragged to safety by Kelly and Yumiko, yelling in desperation for his girlfriend as Jules is devoured, beyond the ability of any of her friends to try to save her. Shooting at a smaller group of walkers coming down an alleyway, Carol orders her friends to follow her down it and everyone flees as the herd overruns the streets.
At the Commonwealth Children's Home, walkers devour a couple of corpses while two more corpses lie in the hallways. Rosita, Eugene and Gabriel enter and Rosita is frantic for her daughter's safety upon seeing the corpses. Hearing the sound of crying, Rosita runs off while Eugene and Gabriel use the bayonets on their AR-15s to dispatch the walkers eating the bodies. In the nursery, Coco, Mariam and Adam are protected by an upside-down crib that has been placed over them while three walkers try to get at the children. Rushing in, Rosita is grabbed by a walker that surprises her, but she manages to break free and put all three down, saving the children. Rosita embraces her daughter as Eugene and Gabriel rush in, relieved to find the children alright and Eugene soothes Mariam while Gabriel joins Rosita with Coco. Ezekiel radios in that they've got Mercer and asks for any updates on the kids. Gabriel reports the good news and Ezekiel promises to see them at the hospital.
At the hospital, as Daryl tries to wake Judith Grimes up, Rosita calls in with the news that her group is in the alley behind the hospital, but they wrecked their ambulance going through the herd which is now surrounded by walkers. Rosita, Eugene and Gabriel burst out of the ambulance, each carrying a child in slings, but find themselves surrounded on all sides by walkers. Fighting back-to-back and saving each other when they fall into danger from walkers, Rosita orders everyone up a nearby drainage pipe to a window. However, while Eugene and Gabriel make it safely, but the walkers drag Rosita backwards and she falls into the herd with Coco. As Eugene and Gabriel mourn for her apparent loss, Rosita suddenly breaks free, slicing a walker's head in two, getting back to her feet and taking out several walkers as they all try to swarm her. Rosita manages to climb on top of the ambulance, followed by two climbers, and successfully makes a jump to the drainpipe where she climbs into the window.
At night, outside of a loading dock, Mercer observes a crowd of desperate Commonwealth residents demanding to be let into the Estates. Mercer reassures Maggie that they will be able to move soon while Aaron tells Ezekiel that he saw people on the higher floors and rooftops begging for help, but he wanted to make sure that Lydia was safe first. Ezekiel reassures his friend that he did the right thing. Hearing screams in the distance, both men are determined to do more, but they need to take care of Judith first. Lieutenant Rose arrives in another truck and reports to Mercer that they're all set: everyone is in the back and there's no one to check. The doctors have set up a safe house, but they have to hurry. Mercer calls for everyone to go, stating that they need to get Judith to Tomi. Everyone boards the truck with Princess, Max and Dianne pushing Judith's stretcher.
At the safe house in the Estates, Eugene sits next to a sleeping Max, but he gets up after noticing how upset Rosita looks as she plays with Coco nearby. Eugene offers to take Coco off of Rosita's hands for a bit so that she can get some rest, but Rosita kindly refuses his offer. Eugene brings up plans for the future, such as teaching Coco how to swim at Oceanside, but Rosita doesn't respond. Eugene begins to go into a scientific explanation as to why teaching Coco to swim as an infant is a good idea, but Rosita continues to fail to respond to him. Rosita wipes away a tear as Eugene asks her if she can't wait for summer and Eugene realizes that something is horribly wrong. Rosita shows Eugene a bite mark on the back of her left shoulder, having been bitten by a walker when she fell. Eugene breaks down in tears, knowing that there's nothing that can be done to save Rosita. Accepting of her fate, Rosita orders Eugene to pull himself together as she doesn't want the others to know yet and she's still there and Eugene will be fine. Eugene admits that he loves Rosita deeply, a sentiment which she returns. Working to compose himself, Eugene returns to Max where he hides the truth, complying with Rosita's wishes.
Suddenly, there's shouts outside and two gunshots. Looking outside, Mercer sees a man trying to climb the wall, only to be shot by Commonwealth soldiers on Pamela's orders. Mercer tells the others that the soldiers are shooting anyone that climbs the gates and grabs a gun, unwilling to just stand by as people are dying. Mercer informs the Coalition members that the truck is gassed up with enough reserves in the rear to get them home. Mercer and his men can sneak them out the back as Mercer believes that this isn't their fight or their people. "Yes, they are. And so are you," states Ezekiel. Addressing the others, Ezekiel tells them that "you may not think this place is worth saving, and I get that, given how they treated us. But it's worth it to me. The people are worth it, and I'm not gonna allow them to fall without a fight. Not today. I'm with you. Who else?" Aaron immediately agrees, stating that they can do more than just save themselves and they need to. Following Ezekiel's lead, everyone agrees to fight to save the Commonwealth.
At the gates of the Estates, the crowd desperately begs Pamela to be let in, amongst them Mr. Martens, Mrs. Martens and Mei. On a balcony, Maggie lines up her shot on Pamela, but Negan tells her to hold on as Mercer and his loyalist forces move in, ordering Colonel Vickers and her men to lower their weapons. Pamela orders Vickers to arrest them, but the Coalition forces join Mercer's troops from another angle, creating a standoff. Pamela accuses Mercer of being a traitor, but Mercer states that she's the true traitor and lists Pamela's crimes: disappearing hundreds of citizens, leading the dead to their doorstep, shooting a child and now leaving thousands to die.
The banging on the gates grows more frantic as the herd begins to approach the Estates, meaning that the people will die if they're not let inside. Gabriel moves towards the gates despite Vickers orders to stop. Gabriel announces that they're opening the gate and letting everyone inside, threatening to kill anyone who tries to stop him. Vickers threatens to shoot him, but Carol warns her that they will fire back if she does. Pamela orders her men to shoot Gabriel as he reaches the gates and one of them points a gun at his head. Suddenly, Daryl yells for them to stop. "What the hell you doing?" Daryl demands. "We all deserve better than this. You built this place to be like the old world. That was the f*ckin' problem." Pamela states that if she opens the gates, the dead will get in too, not just the living. Daryl tells her that if she doesn't, Pamela will lose everything anyway. "We got one enemy. We ain't the walking dead."
Realizing that Daryl is right, Vickers orders everyone to lower their weapons and give Gabriel the key to the gates. Everyone stands down and Vickers defers to Mercer's command who places Pamela under arrest for high crimes against the people of the Commonwealth. As everyone rushes to help let the people in, Maggie informs Negan that Pamela is getting arrested and Negan tells her that prison is a fate worse than death for someone like Pamela, causing Maggie to relent in shooting her.
The crowd rushes in just in the nick of time, amongst them Jerry and Elijah, before the gates are closed, keeping out the herd. Elijah reunites with a relieved Lydia while Jerry desperately looks for his family before Ezekiel reassures his friend that they're safe back in Alexandria and that they will get back out there to help the people that still need their help. Approaching the gates, Pamela notices a zombified Lance Hornsby, Carol's arrow still in his neck, at the front of the herd, reaching through the gates. Pamela approaches Lance, baring her neck and intending to have Lance bite her as a form of suicide. Judith begs Pamela not to go through with it as it's never too late and they have to help everyone still out there. Before Lance can bite Pamela, Maggie shoots him in the head with her sniper rife, putting Lance down. Maggie states that it's time to take the Commonwealth back.
With the variants being too dangerous to just lead away, Mercer outlines a new plan as everyone rushes to carry out his orders. As they need to get a vehicle out of the Estates, a mixture of Coalition forces, Commonwealth soldiers and Commonwealth residents, led by Aaron, rush out of the Estates, armed with melee weapons and riot shields with the aim of drawing the herd away and clearing a path, although Mercer warns them not to engage the walkers more than absolutely necessary. Working together, the group holds the line against the herd while Mercer calls in that the vehicle is out of the back gate and on its way to the town square, asking them to let him know when they're clear. Magna reports that they've diverted the walkers and its clear as it's going to get, ordering them to move out. As the combined group continues to fight the walkers, the truck by through the cleared path to the fuel depot where Vickers, Ezekiel, Jerry, Dianne and several Commonwealth soldiers collect the fuel. Max reports in that they've got fuses running to the private sewers under the Estates and they'll finish wiring the rest once they get the fuel back while Princess goes to start the PA system to draw all of the walkers to the Estates.
Using Pamela's record player, the song "Cult of Personality" is blasted throughout the Commonwealth from the Estates, drawing all of the walkers overrunning the Commonwealth towards it. Elijah helps set up speakers throughout the Estates as Jerry, Ezekiel and Lydia pour fuel down into the sewers and the walkers fighting the forces outside of the Estates begin moving towards it as well. Mercer brings out some dynamite which Eugene and Yumiko help to wire up to drums of fuel placed throughout the Estates and Connie helps to wire up more speakers, unharmed by the loud music due to her deafness. As Max helps to coordinate the efforts, Mercer calls in that they're prepared to open the gates and to let him know when they're ready. Max calls in that they're good to go before she joins the others in retreating to the rendezvous point, the two women acknowledging that they're dead if this plan fails. The gates are opened and the herd floods into the Estates. Once the song ends, the fuses connected to explosives inside of Pamela's house are ignited, detonating the fuel in a chain reaction that obliterates the Estates and the entire herd, saving the Commonwealth.
In Alexandria, everyone enjoys a celebration and feast, joined by Mercer, Max and Tomi. Judith gives Dog some of her food and Yumiko raises a toast to Luke. Looking out the window, Daryl sees Negan walking away and the two men exchange a smile and a nod, parting on good terms. Yumiko turns to Magna, telling her "same" and Magna kisses her, the two women resuming their romantic relationship. Sitting down, Rosita smiles as she watches the celebration before becoming somber. Noticing Rosita's somber mood, Gabriel joins her, and Rosita tells him that she just wants to remember this perfect moment. In a whisper, Rosita reveals her bite and impending death to Gabriel. Noticing Rosita's behavior and crying, Judith realizes that something's wrong with her and becomes upset, apparently deducing the truth.
Weak and near death, Rosita is led to bed by Maggie and Carol where Coco is laying. With everyone now aware that Rosita's dying, a tearful Maggie gives her a hug and kiss goodbye and Carol hugs her before the two women leave. As Daryl watches from the doorway, a barely composed Gabriel performs Last Rites over Rosita. Rosita kisses Coco for a final time and Gabriel promises that they will see her again someday. Gabriel carries Coco out as Eugene takes a seat next to Rosita's bed. Eugene tearfully tells Rosita that he wouldn't be the man that he is today if he hadn't met her. Taking Eugene's hand, Rosita tells him that she's glad that it was him in the end who will be there to make sure that she won't reanimate after she's gone. Rosita peacefully passes away with her oldest living friend at her side.
A year later, Rosita's name is on a memorial plaque for those lost in the walker invasion with her name beside those of Luke, Jules and Marissa Berot. Eugene lays down flowers for his lost friends before pressing a kiss to Rosita's name.
