Lets just say this. Season 3 will be epic for so many reasons. The prison, villian, and new characters all take the concept to a whole new level.
This is the pessimist in me but revealing that everyone is infected downgrades the whole show/concept for me because what are they f!ghting for? It may have been survival but now what is it hope?
Michonne is/or has the possibility to be the greatest character because she is possibly the only character who can match Rick.
Also, Andrea is one of my favorite comic book characters but really dislike the actress (Laurie Holden).
