So... HIS part of the floor was clean. He wasn't gonna clean the whole thing, because this was a team effort, you know. Theo stopped and surveyed what he had already done, then looked over at the board to refresh his memory of the polishing spell. It was hard since he was all the way over here and on his knees, but he seemed to have a good idea of what to do. He'd done this before, so he could totally do it again!

"Polio-tus." He said aloud.

Okay. Theo practiced the 'S' wand movement, too, and soon felt ready. "Poliotus." He lagged a bit, but proceeded to do the movement. But nothing happened, OF COURSE. The Slytherin frowned at the floor but wasn't going to give up that easily. This time, he tried his hardest to do the wand movement and the incantation at the same time.

"Poliotus!" Sssssssssssssssssssssss...

And viola! The floor was suddenly gleaming up at him. Almost enough to see his own reflection. Nice one, Kinsley.
