It would probably be the happiest moment of Roland’s life. He’d probably cry when Dante says “I do”.

Also, he’d make obscene gestures when Dante wasn’t looking towards Tev, gloating about the hot wedding night they’ll have

Wwwwooooow Tev doesn’t want to hear about that at all. (But secrely he’s glad because now every time Dante hits on him he can remind Dante that he’s married. Roland might receive some anonymous tips on things to do to Dante.)
