when does the governor come back in season 4
The Governor (The Walking Dead) "Live Bait" reveals that, just after massacring his own people, the Governor sets up camp with Martinez and Shumpert. Martinez and Shumpert abandon him after he does nothing to protect himself from a walker, believing him to have lost his nerve. The next day the Governor drives back to Woodbury, which is overrun with walkers, and burns down the entire town. After several months alone, intentionally trying to let the walkers kill him, he finally collapses on the street. He looks up to see a young girl, about the same age as Penny, in the window of a nearby apartment building; he pulls himself back to his feet and investigates. He finds the Chambler family residing inside, consisting of sisters Lilly and Tara, their father David, and Lilly's daughter Meghan. Lilly and Tara initially hold the Governor at gunpoint, but they later confiscate his pistol and allow him to stay in an apartment across the hallway. After hearing about how the Governor has survived the last few months, they ask him his name. He tells them that it is "Brian Heriot", a name he saw painted on the side of a barn while staggering aimlessly through the countryside. He runs some errands for the family, and risks his life to get David two oxygen tanks from a walker-infested nursing home. When David dies and reanimates, the Governor saves the rest of the family by bashing in David's head with one of the oxygen tanks. After he buries David, he burns his photo of his wife and Penny. That night, he goes to the Chamblers to say goodbye, but Lilly insists that he stay. He and Lilly become lovers, and he saves Meghan when she falls into a pit of walkers, killing them with his bare hands. Moments later, he encounters Martinez and his group.
