ok,Are'nt claire and sylar were related, isnt he her uncle or something like that??? i really hope im wrong..if hes going to try and get with her

No, they are not related. I can understand the confusion. Momma Petrelli did a number on Sylar once, made him think she was his mom. He eventually saw thru that lie. Claire and Sylar are free to explore a relationship. However, I don't really see Claire warming up to him...unless it's against her will.
