I'm looking for a fic that takes place in The French Mistake and in which sam and dean find out that Jensen is either dating or married to misha in a way similar to when they find out about jared and genevieve. But not the misha from that that episode but a version more similar to the real misha with all the sarcasm and oddities. Perhaps dean plays along because misha looks like cass whom he's in a relationship with or simply to not9t mess things up much doesn't matter.
