I'm looking for the following types:
1. Dean self-harming and Sam or John don't notice at first until it gets really bad.
2. Dean gets de-aged and Sam is really protective of his little, big brother. Preferably a longer fic with Dean as a kid for a long time.
3. Sad sick!Dean stories where Dean almost dies and Sam and John and maybe Bobby too. I would prefer for Dean to go unnoticed or neglected before they find out he's sick.
4. Dean finds out he has powers and he is in more trouble than Sam because of it. Or maybe he kicks some ass with his new powers
I would prefer gen, but slash would be fine as long as it is not wincest.
