Sam in Hospital

[findmeastory]

Looking for a story I read sometime ago, thought I bookmarked it but now can't find it.  Sam is in the hospital following a head injury I believe.  As he wakes up he hears Dean saying that he wished Sam was still a kid and needed him to take care of him.   Sam decides to give him his wish and pretends to have brain damage and reverts back to a young child.
