After viewing this weeks episode Arrow on the doorpost, I noticed a change in Milton's chracter. I could see him being more humane, understanding and generally growing into the opposite of the Governor. Could he be the dissenter or the traitor in the description of the next episode Prey? Also in the promos we see Milton being pushed and overpowered by the Governor, willl this strain their relationship and make Milton want to leave and join Rick to warn him about valuable information he may need? He's got a good thing going with Herschel too :p
Side note: Also in the promos for Prey we see Andrea warning Tyreese and Sasha about the Governors ways. Would this persuade Tyreeses' group to leave Woodbury, possibly with Milton to lead him to the prison?
