maybe i missed something but..
didn't Simone become human again after Vlad died? it was specifically stated by Simone herself that Lazlo/Vlad was the vampire who turned her 400 yrs ago and we all know that all vampires turned by a certain other vampire will 'un-vampire' once their 'turner' is killed. yet, she still dissolved when the sun came up as if she was still a vampire.
another unrelated point. this evil Russian guy doesn't like his country's current government so naturally his solution is to reincarnate Vlad the vampire? yeah, that would be my first thought.
