I haven't decided about messing him up yet - I have a head canon that most of the suffering they must have put Sam through in the Cage would have been mental rather than physical, and that his body although it was actually physically there (somehow) would be kept young and pristine. Otherwise, how did he come out the same age he went in when he was there for two centuries...?

Mmm I wonder how one could show memories in this... ponders....
