I think I know the reason. I 愛 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 愛 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 ファン can't ignore. So that leaves us with the ultimate question, who's it gonna be, nair または chair. Although most of us think it'll be chair, there's still that chance that nair could fall back in 愛 like in the books, and crush all of us chair fans. They, wouldn't do that, the writers know we all 愛 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.
