Sirius wished that was a favour he could do for her, but he couldn't. He shook his head. "Unfortunately, I can't forgive the detentions. The two of you should have been expelled, to be honest, and my position is precarious enough as it is without forgiving her detentions. I can, however, try and get her in as many as possible with myself, Professor Sprout, and Professor Grubbly-Plank, if that works." He didn't believe in whipping or this kind of punishment at all.
