They were actually doing this? YES--what lint roller?

Was Mo seeing things? She didn't remember the Professor letting any of those out of the box thing but not all Ravenclaws spoke in rubbish code so Lex twisted trying to see what he might have been on about. As it turned out there WAS a lint roller. Huh, would you look at , something else for them to aim at.

"Alright then," dragon dung, nope, not her, "Impedimenta!" No need for sneaking with this one and if she did happen to catch it the Professor might not realize if it was done non-verbally...though with everyone aiming at the same time...it was still sketchy...

Eh, she'd leave the details for someone else while hoping she got this one.
