Halward's blood magic ritual wasn't intended to change Dorian's orientation, it was intended to change his sex. When Dorian escapes and leaves the ritual half-completed, he leaves with a surprise: he can become pregnant, but without the necessary mechanisms in place... it's slowly killing him.

The Iron Bull is a firefighter with scars and history to spare. Dorian keeps setting things on fire- like curtains, and dates. Or, the one where two messed up people find each other, Solas is a righteous avenger, Cullen really needs to stop online dating, and everyone gets a happy ending but not without some pain to go with it.
