So Adina here really has a thing against vampires. Had a really bad experience with one so she is very cautious and doesn't really trust them. Her wardrobe is very frumpy so it could be funny if Alyson offered to give her a makeover and Adina is freaking out the whole time.
So she and Jasper come from the same high society circles. He's from Boston, but I'm sure that their parents went to the same parties and social functions. She might have been one of the girls his parents forced him to talk to...reluctantly. He doesn't like most people anyone...except his beloved Kendra who's he's been hung up on since the moment he first laid eyes on her. So it might be interesting if they ran into each other around them. Or found out about his infatuation.
And my last fellow is Dallas Gurule, he's 1,351 years old an is a half demon. He recently has lost his immortality as it was sacrificed to bring his sister back to life. He is the department head of the magic side of the Adam's Foundation. He teaches elemental magic, offensive magic, and also some self defense classes. Being a vampire she'd be with the stronger of the bunch.
