She had let Leobald and a few students go first, figuring she could bring up the rear. Just in case something tried to attack them from the rear. Not that she thought something really would, but her recent encounter with the nifflers in the Chamber had led her to be more suspicious than normal.

She wound her way down the steep, spiral stairs, all the while imagining the floor giving way and half of Ravenclaw House plummeting towards the ground. Cushioning Charm for sure.

Her hand brushed up against the wall and she recoiled at the wet, slimy feeling. "And I think we're underground." Definitely time to wipe her hand off on her robes.
