Mikhail was inclined to say that Fenrir was the one that was dangerous, not the other werewolves here. Then again. . .they were untrained beings. So he got up and moved around the desk to pat a friendly hand on Fenrir's shoulder.
"Promise is all ask," he said honestly. But his face darkened when he thought about the fact that his sponsee was the one that had vandalized his room. Shaking his head in disappointment that a child could be so rude to the wise, he sighed.
"Student who vandilize. . .my student. I see to punishment. I not say justice be served, but she not get off lightly. Ticking off wolf is bad idea, full or half." He smiled in that "we have something of an inside joke" sort of way as he took his hand back. "I sorry week so shitty. Will get better. I hope." Mikhail gave another grin, because he was generally a good sort of guy when he wasn't being a quiet, reserved, Navy man.
