During the "A Night to Remember", there's the part with the wedding ring and the marriage. So, I want that male Dragonborn is married to Vilkas during this quest. Somehow, Vilkas learns about this "marriage" (hears of it because Ysolda maybe)and becomes worried/jealous.
After the quest, Dragonborn comes home to a angry husband and has to tell everything that happened.

Bonus points if:
- Dragonborn is a nord/imperial
- Vilkas thinks that DB is going to marry one of his followers
- Happy husbands have sex in the end
