Wow, saw it, and it was intense.
Sorry, but, I gotta say I'm sure Shane knew exactly what he was doing shooting Otis in the leg, rather than killing him, IMHO, it was very obvious.
Andrea, please continue outta the dark side next week, I love ya, but, you were getting on my nerves the last couple of episodes
Shane - not sure I'd call it guilt? He seems pretty Sociopathic to me, I think he's more worried about being exposed or "caught" then he is sorry about the things he does. Lori, he wanted to continue it, and get away with it, Otis he shaves his head to hide the patch ripped out, instead of explaining it away.
