The director of this episode was on the Talking Dead and he said Carl did put a bullet in Lori's head and the bloated zombie did eat her.
Yep. They should've fed him to the walkers on that rooftop. Not killing him has come back to bite them in the ass. But on the other hand, how will things play out once him and Daryl see each other again?
I'm wondering that too. The group is already outmanned and outgunned, but they have no shot if Daryl defects. My guess is that his loyalty to the group, specifically Carol, will override any feelings he has towards his abusive brother. Gonna be interesting to see how it plays out. The show this Sunday is going to reveal alot.
