The window sill was clean and safe for climbing again, and Mo scrambled back up to wiggle the window open a little bit further. Now he could properly see the sky and the grounds, although he probably wasn't supposed to hang out of the window like this. For a good cause, though, right?

Especially because the best way to keep the window frame from further weather damage was to make it completely impervious to the elements. With his head and arm still sticking out the window, Mo awkwardly pointed back at the frame with his wand, mostly casting in the right direction. "Impervius." And now to the other side of the frame. "Impervius."

And now to the inside... erm. Was his head stuck in the window? Was that really what was happening here? He wiggled again at the window until it opened far enough to jerk his head back through, although he nearly lost an ear in the process.

Ouch. "Impervius." He cast the inside of the frame too. Ouch ouch ouch.
