"With The Governor busy pursuing a runaway dissenter, a traitor looks to sabotage his plans."

I wanted to discuss the synopsis of the episode "Prey", which is due to air in two weeks. We all know Rick and the Governor will be meeting for the first time on this week's episode, but I'm trying to figure out who the dissenter is, and who the traitor is.

My guess is Rick is the dissenter, and Andrea is the traitor.

Thoughts?
