I'm not worried so much as bothered. There's no doubt that getting under people's skin is something Teddy enjoys - nay, excels at! - but it isn't like him to gloat without good reason. And what could he mean, "the truth about Draco?"

What I mean to say is, Draco has always made it clear to me that he has certain secrets. I don't know what those secrets are, but could it be that Teddy found them out, somehow?
