I really like where season is at right now - with Carol being kicked out of the group by Rick. I think he did the right thing, as if he didn't, Tyrese would eat her alive. And Rick also had to consider that she might even put his kids down if she thought they were a threat. So... sucks, but I thought that it was realistic.
We obviously haven't seen the last of her yet... I wonder what Rick's gonna tell the group. Darryl and Tyrese's reactions should be good.
