My assumption is this:
The wolves are a group of exiled Alexandrians. Clearly bad news, tying women up to trees to be fed upon, carving W's into walkers foreheads etc. They wont be good people. Daryl and Aaron saw a glimpse of their campfire I believe, or maybe it was Morgan.
I also think that Carl's new gal pal was or is part of that group. Maybe she is a spy, maybe she fled them in fear for her life.
Rick wont end up getting kicked out. "Something" is going to happen next week to open Deanna's eyes a little towards Rick's way of thinking. I have an idea as to what but won't ruin it for anyone.
I don't know who is going to die next week, they are doing a terrific job at making even the graphic novel fans guessing.
