Merle and another guy open the dungeon, probably expecting a docile and defeated pair of prisoners. Instead, Glenn and Maggie rush out in attack mode, Glenn mixing it up with Merle while Maggie jams her arm-bones into the other man's jugular, slashing deep and sending him sinking to the floor while the machine gun in his hand goes off. The group hears the gunfire -- hell, the whole town does -- and they start making their move while other townspeople rush to the wall, which is where they think the trouble is. After more fighting, Merle finally gets his bayonet to Glenn's throat, but Maggie gets the drop on him and orders Merle to let Glenn go. "Okay!" Merle smiles as other armed men come in, locked and loaded. Does this mean they don't get to go to the Screaming Pits?
Somehow Rick and his group have found their way through the town's catacombs (don't ask me why a small Georgian town has both a Main Street and catacombs) to a space adjoining the one where Glenn and Maggie are being held on their knees, although they hang back out of sight while Rick reads the situation. Getting his Bond-villain on, Merle tells his guests he's glad they could catch up. Maggie tells Glenn she loves him, and bags are thrown over both their heads as they're dragged to their feet. Rick and the group realize this is their moment, and they throw some flash-bang grenades and then quickly drag their people free from the smoky room while Merle and the Woodburyans cough and choke in the blinding smoke. No, Rick and his people don't have gas masks, but this must be a kind of weapon that doesn't work on the people who are using it.
Out on the street, Andrea offers to go check it out, but the Governor says he's on it. "No need for anyone to panic," he says. Right on cue, a woman screams, "Someone help!" The man Rick's group encountered earlier is sitting in the doorway, and he tells the Governor that "six or seven guys" he'd never seen before just came through there with guns. A worried crowd is gathering, wondering what's going on, but the Governor tells them all to get inside and lock their doors. Except the members of the guard, to whom he gives orders to shoot to kill.
Rick and his group manage to get as far as a restaurant before hearing the alarm and ducking into a closed restaurant with quilts over the windows. "Rick, how'd you find us?" Maggie demands. Right now they're more worried about where Michonne is. Well, except for Rick, who says she's on her own, because they have to get their people back. Glenn tells Daryl, "This was Merle... He did this. He threw a walker at me. He was going to execute us." Daryl asks if this means his brother's the Governor, which evokes a whole alternate universe for a moment there, but Maggie says that's someone else. "Your brother's his lieutenant or something." Daryl asks if Merle knows he's with them. "He does now," Glenn says. "Rick, I'm sorry, we told him where the prison was. We couldn't hold out." Rick says there's no need to apologize; they just need to get back. Daryl wants to see Merle and try to work this out, but Rick says this isn't the time. "We're in hostile territory." He tells Daryl he needs him. "Are you with me?" Daryl says he is.
