Specific search: French Mistake!verse, Jensen/Misha, Castiel/Dean
Hey, so there's this one really good French Mistake!verse story that features Sam and Dean staying in the French Mistake universe longer than canon. After Misha is killed, it turns out that Gabriel is alive in that universe and brings Misha back to life, after which Dean gets to know him better. It turns out that Misha is in love with Jensen, but Jensen is in denial of his feelings and is a total jerk to Misha, cue Misha and Dean having sex. At the very end, Dean, Sam, and Gabriel go back to their world and Jensen starts dating Misha. Castiel and Dean still have tons of UST between them, though. Oh, and there's some Balthazar/Gabriel in there as well.
