Yeah, I think I'm with cookie_simone. It's not the canon het itself that bothers me, it's how they're doing it. But I've always said that Heroes sucks at writing romance in general - other than Nathan/Heidi, Niki/DL and Bennet/Sandra (the couples that were already established so they didn't have to 'work' at) I don't think they've ever had a romantic relationship on the show that I've bought into. :/
