He hadn't exactly expected to be in here this morning; he'd just been on his way to the Staff room, winding his way down the long hallways and stairs, when Morgan had swooped out of a side passage and told him to mind the Library while he dealt with an issue. Tapendra had agreed..in the form of a surprised nod. That had been good enough for Landis, apparently.
It wasn't like he minded, really, though he seemed to find himself in here often. Maybe being one of the only teachers who had a basically free schedule during the days wasn't such a good thing. It certainly made him the more likely candidate to fill in when Landis had a family emergency.
He'd given himself a job, though - putting books away. There was a rather large pile of them as the students hurried to revise for the upcoming exams.
So when he was trying to remember if a Potioneering Guide to Herbology went under Herbology or Potions, he also wasn't paying attention. The large stack of books in his hands didn't help the situation, as when Arianna collided with him he promptly dropped them. Many of them landed on his bare feet.
"F-" He made a sound that, thank Merlin, didn't turn into a word. "Argghh," he said instead, mouth open in an attempt to just let the urge to cuss dissipate. "Ouch," he said, finally, before he looked down at who'd run into him.
