It is odd that there were no bones left from Lori. Where did Carol go?
The fat (re:engorged seated/lethargic zombie that Rick killed) ate her. If you look closely you can see long woman’s hair in his mouth. If you watch the Talking Dead after show, they answer a lot of questions about the show and show exclusive upcoming previews. Really good show. It provides some comic relief to what is otherwise a very depressing show at times.
