Jacques Villareal will go looking for his dad - and finds out he's Vlad. Then he'll move in with Vlad and bring Luna and Max.
(Hugo will stay in the large house back in Winedenburg- he's a criminal thug who really loves cooking for his mafia friends. He's also engaged to Angela Pleasant, who isn't as sweet as she thinks she is.)
The townie siblings: I think the girl vampire will date Alexander Goth and turn him. Alexander will get the family vampire aspiration. Luna will "betray" her noble family by being a "good" (eating fruit) vampire and dating the guy.
Max will have a lot of fun with his new powers.
