Photos from tonight's 'Walking Dead': Is Andrea the "Prey"?

The second half of AMC's The Walking Dead has pretty much turned into The Andrea Show. Some fansare quite disappointed with this fact, complaining about the character's annoying stubbornness and idealism. But, to be fair, Andrea (played by Laurie Holden) has become more tolerable in these past few episodes. Her attempt to broker a peace treaty between Rick and the Governor was naive, certainly, but at least Andrea was actively doing something. It appears that tonight's episode, "Prey," will see Andrea taking an active role yet again, according to some promotional photos from the episode. 

The episode synopsis reads, "The Governor chases a dissenter who fled Woodbury. While the Governor is gone, a traitor tries to sabotage his upcoming plans." But who is the dissenter? And who is the saboteur? Our money is on the dissenter being either Tyreese (Chad Coleman) or Milton (Dallas Roberts) -- one of which has a significantly greater chance of eluding the Governor. 

But these promotional photos seem to indicate that Andrea is the saboteur who is trying to destroy the Governor's plans to attack the prison. If it isn't her, she'll be doing a hell of a lot of unnecessary sneaking around tonight.

Check out the photos from tonight's episode below. What do you think? What are your guesses?

"Prey" airs tonight at 9/8c on AMC.
