This one was fairly heartbreaking - not that all of the volumes thus far don't have sad moments, but you get numbed to them. It's been a while since I read vol. 10 so I wasn't quite prepared for the deaths that occurred, even though I knew about them in advance. Dale was always a favourite, and the way he died was ridiculously moving - usually deaths just happen and people keep running, but here the fact that they all had a moment to breathe means that it hit a lot harder, I think.
I don't like what's happening to Carl - I'm glad that he showed some child-like (even human) emotion at the very end. He's also a favourite so I don't want him to become completely unlikeable.
The stalker aspect was well done, I thought. Cannibalism hasn't really been seen yet, though it makes sense in Kirkman's world, and I'm glad that that was established as a line that shall not be crossed. The gruesome deaths were perhaps unnecessary, but the remorse and disgust shown by Rick was good, I think. He hasn't completely lost it yet.
I wan more Glen and Maggie though!
