I can't speak for Tristan, but Dahlia might be too forgiving of people for her own good. I think she is fond of several people (NPCs included) that aren't necessarily fond of her. I don't mind if Asuran is a little biased against Greedans, but he is going to be shocked at how perhaps overly accepting Dahlia is. She's what happens when you have a complex and base your self-worth against your relationships with others!
