It was good to see Morgan again. Loved how bad he was with the staff, how he saved the day for Daryl and Aaron. I hope what he walked into at Alexandria doesn't offend the whole "all life is precious" thing too badly.
I hated losing Reg. He was a really likeable character, a real voice of reason among the "native" Alexandrians. I guess his death assures that Rick and the gang aren't getting kicked out, though. I wonder how much longer Carol will play the soccer mom role now?
I don't know how scared I am of the "Wolves" at this point. So far, they're two guys with a cool walker trap and an empty gun, but we know that they overran at least one settlement. I'm sure we'll learn more about them next season.
