Christie here, with her last, and a hufflepuff at that!
Jalal (Jay) Zabini, is a 7th year Hufflepuff whose father owns wizarding casinos and resorts in Monoco. He's a halfblood who believes himself to be pure. He enjoys beaches, ladies, gambling, and transfiguration. He enjoys quidditch, but doesn't play because then it would be unethical to run a book :D
He's rich, accomodating, hardworking, and poised to inherit bank, ladies! He also probably is the sort who could lose himself in a relationship. He runs a poker game, guys who like that sort of thing. It's invite only, but, those interested could probably score invites.
And, I put too much lime in my mojito :< So! Plots? Friends? Rivals? Current/Future/Past flings? LoveInterestsWhoWon'tKillHim?
