Harry had his suspicions.

There was something strange about the way Draco never seemed to eat or drink. The way he was always awake when Harry went to sleep and when he woke up. Maybe it was his pale white, ice-cold skin or his colored contacts.

Perhaps it was his unearthly strength and the way he simply laughed off any comments on it. It was there in his mysterious weekend camping trips that he insisted on taking alone. The way he always told Harry how delicate he was and how careful Draco was around him.

Maybe it was the way he sometimes came up behind Harry to smell him appreciatively, saying gently, "You smell good enough to eat." Then stalking off smirking.

Harry stared down at the book in his hands and laughed.

Oh yes, Harry had his suspicions.
