It is very very late and I need to go to bed but the person who was the 5th year perfect when Albus Dumbledore was a 4th year has decided that screw it, Albus is coming out of his post-Gellert funk right damn now.

He was the one they all referred to as The Demon Prefect.

He always knew just who was up to what.

His name is Bertram Harroway and Albus had the biggest pash on him.

Still might, come to think of it. :)
