2) Anything where the boys have a hell hound as a pet
3)a) Bad-ass and/or assassin Dean
b) Subsequently: other hunters knowing how Dean is a force to be reckoned with (à la beginning of Dark Side of the Moon)
4) This is one of those "out there"... if ANYBODY did anything similar to this, it would be awesome: Dean or Sam in a mental hospital (but don't know it) and the other brother (the one not in the mental hospital) doesn't actually exist anywhere but in the mind of the brother in the insane asylum... So if there are any stories out there with anything similar, my first-born is yours
prefer slash (Dean/Cas or Wincest) or gen... and self-recs are self-love
PS: I think I got all the tags, if I missed any, sorry...
