If you romance Iron Bull, and you also take him and Cole out with you on missions, this little gem of a conversation happens. It's pretty revealing:
Kinky, huh? I'm not surprised that someone has banged on the war table, but damn, guys!
That's not the only instance of risque dialogue with Iron Bull. If you don't pursue his romance, and you don't pursue Dorian, they will start a fling — and Bull is not discreet about it. It's amazing:
