I have a few general searches:

1) Anything where Dean is abused by someone but keeps it a secret from everyone, but then when they're adults someone (John, Sam, Bobby etc.) finds out and comforts him.

2) Something where Dean suffers through really bad abuse in order to protect Sam from it (preferably teenchester or weechester).

3) Dean or Sam is being abused by John and the other finds out.

If anyone could help me out that'd be great!
