And I think Dom would like Zach. He's kind of shallow and doesn't like getting into tussles with people. He's usually paying off people to get him out of those situations.
Dom's dad would probably agree with you, and Dom would as well to some extent. He loves his mommy, but only because she gave birth to him. It's in his history, they had a serious falling out over her selfishness and general horrible being a human-ness. I think that they could still be feuding, but he could be trying to make up for it a TAD bit here and there.
He wouldn't like Dorian, because he doesn't like him. So there!
He would definitely like Nora. Maybe a lot, and probably be jealous of her strange attraction to Jack. Because he personally thinks an Elitist and a Prince would mesh so much better. So I see future problems there, but in a good way??
I think he'd enjoy having her around and as a friend. And he would be just as entertained with her as she is of him. I see maybe even a little crush, which he will take over board with presents and pretty words.
