The struggle is how rick and crew perceives the others as weak and unable. A good preview is the douche son getting punked by Glenn. Take that times infinity and along with the struggle of rick to go ahead and take over vs wait and see but possibly putting everyone at risk in doing so, is probably the main theme going forward until the wolves come fully into play. I don't think he takes over because doing so would basically end the show, unless he takes over and makes a huge mistake that loses everything for everyone and they take off again.
As for the wolves, I also think the girl is a plant for the wolves and will have some dumbass struggle about letting them in vs liking Carl. That has to be the reason she secretly leaves and comes back. Earlier in the show, it is mentioned that anyone can check out their weapon and go out the gate when they want to, but that they have to check it back in when back inside. If the girl can leave whenevs she wants, why else would she be climbing the fence to get out unless she doesn't want anyone knowing. The Wolves will def be the reason something happens to either push rick over the take control edge or Rick's mistake that blows crap apart, imo.
Also, Carol is totally going to be heavily involved in taking the place over, if that is what happens.
