It seems that I don't ask questions as thoroughly as others and I might have missed something.
I was always under the assumption that
a) Clem's parents were bit/dead
b) The reason she thought that they were in Savannah was because she was talking to RadioBastard about where they were headed and like a good little paedo, he made up the bit about them being safe with him.
However reading other people on here mention about Molly telling everyone about her sex favours with the Doc for meds... (missed that completely) and how her parent(s) are in Savannah after all, I feel i've not had some of the dialogue others have.
