Hellooo... I could have sworn I'd commented on this thread before, but given that it's not on my 'Threads I'm on list', Ive realised I may have just been lurking all along....
I LOVED that episode. I love Carryl, and love that we had a bit of good old fashioned zombie action.
I laughed out loud when the walker fell head first onto the van windscreen.. splat! And I liked the zombies in sleepings bags. I too wondered how they hell they turned in a tent, but the shooting theory works.
I didn't see any sexual tension (but I did spot the tank, yay me!), I think they just really 'get' each other.
I think it was Darryl's 'survivors of child abuse book' 
One thing I love about him is that he's so non-judgemental now. He just accepts what people have done and moves on.
I was shocked at Carol's bit at the end. I assumed she'd Trojan-Horsed herself into the hospital, but apparently not.
I loved the comment from Darryl "What do we need to get in there?, Noah "Guns and people"... Darryl "We've got both" or something.. yaaaay, bring on the cavalry.
If Beth lives and Carol dies I'll be REALLY pissed off.
