Deciding that it was the glass polishing charm that he needed extra work on, Theo made his way over to another abandoned window. But it was obvious by his expression that he was getting bored with these spells and fast. He hadn't even seen some of those new looking spells that were optional before.... but he was SO gonna have a go, because they could come in handy just as much as anything else.

Oh... wait... what was that spell again?

It began with a V, or something.

Sighing loudly, Theo looked over at the board again for clarification. It annoyed him how much he relied on these visual prompts. They would get him NOWHERE in real life, you know, because they weren't there! Vitrumonia. Of course, that was it.

The Slytherin nodded and pulled out his wand again, remembering the wand movement as he did so. He liked this movement, it was pretty simple. "Vitrumonia." He waved his wand anxiously, but nope. Nothing... "Vitrumonia!" And again... he waved it... and a small patch of the outside was suddenly in view. WOOT, he had done it. Theo continued to wave the wand until the whole of the window was clear. He peeked outside and made a small whimper noise because he craved the fresh air.

Instead of this dust-ridden air in HERE, that is.
