I felt hugely sorry for Lori! I just don't get the Lori-hate, you guys! She had so many miserable things happen to her and now this. But I wasn't clear that she truly died, either. She was certainly losing a lot of blood, but I think I would have tried to go back and save her. I mean, it's not like they ever took a pulse or anything. They just showed her losing consciousness. You can lose a lot of blood and still survive...
If Carl did shoot her, I think it was a little trigger-happy. But it was such a shocking situation for him, too. But now... a newborn. Yikes. What a nightmare.
