Hershel probably tops the list. I don't want it to happen, but I think it has to. If they're truly abandoning this place, and I think they have to, life on the road won't be friendly to him. There's every chance that he could be a hindrance to the group, including the two people he loves most: his daughters. He said it himself this past episode. There's nothing he wouldn't do to keep them safe. I think that's gonna be going out fighting, preferably taking out as many Woodbury folk as possible.
