I think I know the reason. I l’amour chuck and Blair, as do most of you. We don't want to betray chair. We think about it like this, Chuck and Blair.. That's it, that's love,that's Gossip Girl. We can't imagine either of them being in l’amour with anyone else. We don't want nair, we want chair! But, there will always be nair. nate and blair will always have history that we chair fans can't ignore. So that leaves us with the ultimate question, who's it gonna be, nair ou chair. Although most of us think it'll be chair, there's still that chance that nair could fall back in l’amour like in the books, and crush all of us chair fans. They, wouldn't do that, the writers know we all l’amour chair, right?? well, the writers always surprise us. I know chuck and blair will end up together, so while we wait, why not give nair a chance to have a cute little fling?? we don't have a choice.
