Julian's head came up at the first sound of shuffling in the vents above his head, tilting one ear towards the ceiling just as the scraping of the screws began.

Something was in that grate. Something, he thought, much larger than a mouse.

There wasn't anyone else in the cafeteria for the moment--he'd waited, purposefully, in hiding until everyone was gone. He hadn't really expected anyone to come in from the ceiling--though he supposed he shouldn't be surprised, at that.

Julian pinpointed the specific section of ventilation shaft the noise was coming from, then ducked behind a set of kitchen appliances out of view. He'd wait, and see who--or what--came out of there before deciding what to do.
