I'll begin:

1. Lacra. Seriously, she makes me cackle every other sentence she says with how sardonic and unapologitically dark her sense of humor is. Exactly my kind of humor, 10/10.
2. Ambrus. He's so over the top in with his manners and presentation, a pretty interesting take on what a nouveau riche vampire would be like.
3. Coen. He's so sweet and sincere you can't help but smile and laugh at some of his out of the loop moments. They've struck a good balance between writing him as a decent village lad who's way out of his depth at first, but is smart and competent enough to figure out how the world works quickly enough to keep up. But he can also be a funny little shit when he wants to.
