On this week's The Walking Dead…
After seeing Martinez round up weapons, Milton reveals to Andrea that the governor made a deal with Rick for Michonne.
Andrea wants to either kill the governor or warn Rick.
Andrea escapes Woodbury after Tyreese and Sasha let her go.
Allen confronts Tyreese about not messing things up which escalates after Tyreese learns that walkers are being kept in a pit to be used to attack the prison.
The Governor hunts down Andrea and manages to capture her right before she reaches the prison. He ties her up and puts her in his secret room, but tells everyone else that he hasn't found her.
Someone, presumably Milton, set fire to the walker pits in an attempt to sabotage the Governor's plan.
