He has some of the qualities Luca has hidden. The being open part. Like when Luca finds out about Lia he'll be surpirsed but wont care she's only half-breed. He may be a bit stuck up and stuff from being a noble and such but that's really within his own race. Like if she was a bitten or a half vampire he'd have a little ego issues he'd struggle with but the fact that she's a totally different race doesn't matter to him.

Alright so down to earth, protective, not regret. I should be able to pull that off.
