What now. Severus stalls when she calls out to him, reeling in the impulse to fall into a defensive mindset. It's not someone who's going to attack him - if it was, he thinks they'd be missing a limb by now. His patience is threadbare.

.. Is it? He glances down. Oh. Right. Severus looks back up at her, expression flat. "Yes." Well. "It seems I've only half-heeded your advice."

He didn't get punched in the medical area, anyway. Severus raises a hand to his face to make sure he's not still got anything on his skin, having only done a quick job of healing himself after he and Sirius finally parted ways. It's fine, though, just the remains on his shirt standing out still. He'll clean it out soon enough but he'd like a mirror, and also to not have to deal with any more former classmates. Ever.
