At last, there was something mischievous to the curl of Gellert's lips. "I stole it from the Durmstrang library, along with several related texts." All regarding Dark magic, of course, though Gellert was not certain he wished to relay as much to this stranger so soon. "They're expelling me, so I felt the exchange was only fair."
His expulsion was not yet official, but Gellert had no doubt that was where these trials were headed. It was the gentlest punishment for his crimes, after all, and Gellert had never been more grateful than he was now for arranging to have the deputy headmaster sleep with him at the end of his third year. Between the man's guilt and Bela's Imperius-influenced testimony, he at least would not have to worry about imprisonment in one of those specialised juvenile rehabilitation centres.
"And where did you find Ulrike?" Gellert asked -- the more salient question, he thought, as the man's accent implied a conservative Hogwarts education.
