re: A theory that was brought up about TWD...non-comic book readers

Isn't there also a theory that Merle is a spy for the Governor's side in the prison? Somehow I find that more believable than Tyrese's group being sent by Rick to infiltrate Woodbury. I think they just left because Rick was acting crazy when he saw Ghost Lori and telling her/them to leave.

It seems obvious that they will tell the Governor's troops the weaknesses of the prison, but I don't see how the Governor would really trust them completely and bring them into his fold so easily though. (I think someone brought that up in last episode's thread. Interesting that the title of the episode was "I ain't a Judas", which could refer to Andrea, Merle, and Tyrese's group, all trying to prove themselves.)
