I was pretty happy overall with this episode, although Andrea is, in my opinion, getting drastically close to Lori-levels of dislike. Yes, her character has been neutered (or spayed) compared to the comic but it's more as to how the actress plays her. Just the way she delivers some of her lines. I like the actress but some of her mannerisms rub me wrong. Nothing that I can specifically point to. Maybe it's just me, though.
And how about Glen getting all badass? First taking out that zombie with a chair, then making a weapon out of it's arm! That was damn creative.
I'm still sticking with my Merle prediction. No way Rick will let him back in the group after what he did to Glen and Maggie. Not even as a hostage. I just can't see it happening.
