The latest episode of The Walking Dead finally saw Rick starting to come out of his insanity haze. This was the first episode since Lori's death that he did not experience any hallucinations, visual or auditory.
As the group ran over their choices concerning the Governor, Rick began walking away. Only Herschel's yelling was able to stop him and force him to re-examine his mental state. Later, as he was inspecting the perimeter, Carl confessed his lack of faith in his father, suggesting that he "take a break" from being the leader.
Meanwhile, Merle seemed to become a permanent resident of the group again, amongst much argument. Glenn didn't protest as much as one would have expected, considering he was beaten and almost killed by Merle. In the end, Merle's knowledge of Woodbury and the Governor's tactics proved his potential value.
Andrea made a short reunion with the group, a failed attempt to reconcile the prison with the town. She returned with the supposed intention of killing the Governor in his sleep. As she stood over him that night, naked and with a knife in her hand, she found she wasn't strong enough to go through with it.
This could mean that Andrea is the new Lori; someone who feels she is in some kind of control, but whose actions and irrationality ultimately slow the group's progress and put its members in jeopardy.
