Dean doesn't feel anything
In the fic Sam has got Dean back, don't think it's from Hell, just some nasty b**ch that has taken him and tortured him, but when Sam gets him back, he begins to see something is wrong with his brother, he doesn't feel any pain, and Sam has to keep a close eye on him because sometimes Dean doesn't realise he's hurt. Hope someone has heard of it and can help out, Thanks to anyone who replies.
