Hello!

I'm looking for any fic where Sam time travelling because of Dean (like maybe Dean's dead in his time so Sam goes back to the past to save him or because he's missing him, or maybe Sam time travelling because Dean went to the dark side and he wants to change it). And I want Sam and Dean have very close relationship (as brothers or lovers). Gen or slash is okay, but if slash and there's sex scene I only accept bottom!Dean.

And I also looking for this particular fic. In that fic, Sam went to dark side (as the Boy King, Lucifer, or whoever he is I don't remember) but he's still love Dean (and obsessed). Then Dean got killed (or maybe destroyed because I remember Sam couldn't get Dean back alive) and Sam went to the past because he wanted his Dean. I remember Sam arrived at Stanford-era and using all the means to make Dean in that timeline his.

Please help me, and thanks in advance!
