He's biting his lip as he looks back at Sirius and tilts his head in a way that might have been an equivalent of a shrug. "Mildly entertaining," he says, a little bit teasingly. He can't help it. He shouldn't be like this with a professor but it's also Sirius...

"You could improve your performance."
