He was still finishing his muffin when the Professor stepped outside and said it was okay to come inside? Yes, that's what he heard.

"Hello, Professor...." er, Treyen eyed the room, there was no sign of his name anywhere, but there were, "...Ducks!" rubber duckies! Like the one he'd just eaten. Well, no, he didn't eat a rubber duck, he just ate the muffin with the duck in it.

"My name is Treyen, Treyen Lockhart and I have come to ask you a question, perhaps you'll be able to help me" he nodded, it was muggle-related sooo perhaps he knew.
