I'm wondering if Dorian's spirit/necromancy magic is going to make him the party's healer? If so he'll be one heck of a snarky doctor:
Dorian: And to think that the Senators droned on about how you lot were invincible grey giants.
Iron Bull: I'd like to see one of your fey little senators try to cold clock a giant.
Dorian: Considering that you fractured your hand in three places I doubt that any of them could do much better.
Iron Bull: You know I'm surprised that they kicked you out of the Imperium what with your sparkling personality.
Dorian: I'm surprised that you haven't regaled me with the story of how your people sew the mouths of their mages shut. Or threatened to wear my scalp as a hairpiece for that matter.
Iron Bull: (laughs) Hm, that second one isn't a bad idea.
Dorian: Well then you sir are clearly a man with excellent taste.
