There was something, well, perfect about Blair and Chuck as a couple – something that no one apart from a writer could see. When they were near each other, there was a sense of electricity in the air. And Dan was quietly convinced that they would combust, and the resulting blaze would either destroy them entirely, or take the other road. Where that road led, no one could know; it was, after all, Chuck and Blair. But one thing that Dan was certain of, was that neither of them would find an adequate replacement for the other. And so they walked around as two halves, and the effect was that of an amputee – the sickening sense of something missing that should be there.
