Snape gasped for air as Yoh slammed him against the wall. He should have known that the brat's older brother would do this, the same kid who attacked someone at the prom with a knife. He should have known. Stupid, stupid. Yoh was just a Muggle, but he was angry, and he surely had a knife, and he was definitely dangerous. Perhaps a bit mad.

Snape lifted his wand ever so slightly, not so much that Yoh could grab it, but enough so he could use it if he had to. When he had to. "Because I can kill you first," Snape choked.

But he wouldn't kill Yoh. He just had to get away from him.
