Of coarse, in more twisted irony, Dexter, Andrew and a defecting Patricia use the guns from the armory to threaten Rick's group into leaving the prison by telling them to "Get the fuck out of my house".
Meanwhile, a mysterious woman accompanied by two chained up, armless, jawless zombies. Hears the sound of gunshots and follows it. She finds Otis on a stagecoach, and shooting a Winshester as he is heading for the prison for safety after having stayed behind at the Greene Family Farm to take care of and manage the livestock. He soon becomes surrounded by zombies. He is rescued by the mysterious woman, Michonne, who kills the zombies.
Inside the prison yards, Patrica, again realizing she made the wrong decision, tells Dexter he isn't suppose kill them. But Dexter pushes her away. Rick demand to know where they got the guns, Dexter says he got them from Block A, which unwittingly unleashes a horde of zombies after Andrew forgot to close the prison doors while gaining weapons from the armory within.
Dexter and Rick are forced to work together to wipe out the zombies. Dexter is seen with M4 Carbine as the weapon he got from Block A. Andrew a AP Pistol.
Johnny, now wearing his LOST MC jacket again, is seen shooting his double barrel. But keeps back a little, cause it's still a double barrel.
Carly shoots the unscooped hunting rifle she earlier got from Dale, and putting a bayonet on it, also using the bayonet on the zombies.
Pinkie is using her MicroSMG, she's gotten pretty good with it. And killed a good many zombies before reloading.
Dash is seen firing her combat shotgun. She loves combat shotguns. And even her condition, she killed a good few of the undead. Sally covering her, with one of the rifles.
Tyreese is using his hammer, he's not the greatest shooter.
As the battle thickens, Dexter is almost bitten by a zombie, but Rick saves him at the last moment. Dexter still refuses to cooperate with Rick, saying a smart man would have let the zombie get him. Unfortantely for him, Rick takes this to heart. And when nobody is looking, Rick shoots Dexter though the head. Looking like he was killed in the crossfire. Only Tyreese notices what really happened.
Patrica cries over Dexter, but Rick coldly says
"Cry me a fucking river, is that all of them?"
Carly shoots the last zombie before saying, "Yeah, that's all of them".
Johnny grabs the M4 Carbinr for himself. He's getting tired of his double barrel, while saying, "Good, we can finally have some piece and quite"
Shortly after, Andrew runs off, never to be seen again. Unlike the show he never returns for revenge, and is assumed to get bitten.
Axel however is allowed into the group. Considering he never did anything bad to them, and even sided with them against Dexter.
Shortly after they allow Otis back in, and sayin Michonne saved him. Rick letter her stay but if she hands over her sword, and that "they" can't come, referring to the zombies.
Coldly, Michonne kills them than and there, shocking Rick. But still she's allowed into the group.
