Good Vampire rewarded with the Cure for Vampirism.

He's my favorite to play, just started a new save with my sim he just got engaged to. I've only seen him not get the cure instantly a few times, tho when he did get it I usually get rid of it and if I change him later will just make a new one (even tho it's not cheap), I just love him as a vampire, he even snuck in to my sims apartment after their date.
