I Fear No Fate, For You Are My Fate - intrepidheart

A well written fanfic in which Sam is a psychologist and Dean a mental patient but only Dean can remember that they are, in fact, brothers. The author voices the guys to perfection.

'Dean isn’t even safe in his own bed with the door locked and the lights turned out. He doesn’t have any room in his head that isn’t filled up with Sam and Sam and Sam, all him, all the time.'
