Maybe, but I don't understand why the Governor hasn't killed him already. The governor knows that Milton told andrea about the plan and knows that Milton burned the zombies, and the Governor, other than looking mad, didn't do anything about it. Why not? Why would he keep Milton--a person who is actively trying to thwart his plans--around? My only guess is that Milton is either related to him or provides some other critical value that we haven't yet seen.
My guess, for what it's worth, is that Milton will let Andrea out.
In terms of series continuation, what would that have accomplished?
We do know that Milton knew the governor before the ZA, so who knows, they could be related in some way. There’s some kind of connection there.
I agree with you that Milton will be the one to find Andrea, and once he’s freed her, Philip’s going to find him and slap him in the chair.
