Carol catches Andrea up about what happened to Lori and T-Dog. And to Shane, after he tried to kill Rick. "He loved Rick," Andrea protests. "Shane loved Lori," Carol shrugs. Still don't know why anyone would. "Rick's become cold, unsteady," Andrea diagnoses while holding his child, and Carol defends him, saying he has his reasons. Carol asks Andrea to do something, and Andrea protests that she's trying. She's sucking, and it's a shitty idea in the first place, but she's trying. But Carol meant something specific: "You need to sleep with [the Governor]. Give him the greatest night of his life. Get him to drop his guard. Then, while he's sleeping, you can end this." Whoa, check out Carol, being of tactical use!
Out in the yard, the group gives Andrea her bag back and a dusty Department of Corrections vehicle from the motor pool. She looks around at everyone, says, "Take care," and gets in. Before she drives off, Rick returns her knife and her gun and tells her to be careful. She drives to the gate, which Merle hurries to open for her and close behind her [Note: I still don't understand why they let the guy with one hand do this. -- Rachel.], and threads through the zombies milling in the outer yard. And without bothering to flatten any of them like a guest with any manners at all would do.
It's full dark by the time Andrea drives her new car right up to the main gate at Woodbury. The guards on the wall all level their weapons as she pulls up, and shine a spotlight through the windshield. She gets out, her hands up, and they recognize her.
And let her in, apparently, because she presents herself at the Governor's apartment, finding him in his cups and listening to a music on an old reel-to-reel recorder because he presumably can't be bothered to loot a Best Buy. She tells him about her little visit. "They're broken. Living in horrible conditions." The Governor asks about Michonne, Merle and Rick, all of whom she confirms were there, and he asks if they sent her back here. She says it was her decision to come back. He asks why, and when she doesn't answer, he gets up to caress her and answers for her, "Because you belong here." They embrace, and it looks like Andrea is going to put at least the first step of Carol's plan into action.
It's night at the prison, not that anybody's sleeping. They're all hanging out in the hallway of the dark cell block like they're already surrounded and under siege. Rick comes out of one of the cells holding Lil Asskicker, and Beth decides to sing everyone a song. Which I later find out is "Hold On," making Beth the youngest, blondest Tom Waits fan ever.
