Okay, yes Char could totally ask questions. Questions were things she had plenty of because she was brought up by Ravenclaw parents and they ALWAYS encouraged her to ask stuff.

Sooooo after taking her robe and cardigan off and neatly rolling her shirt sleeves up to be a bit more comfy, Char put her hand up.

"Professor does climate have any impact on spell casting? At all? Or like different ones more than others?" Because why else would they have it all weird in transfiguration unless they were supposed to be trying to get around the temperature and humidity? All the spells she could think of that would make it more comfy were charms after all, rather than transfiguration spells and OOOH maybe they would get to conjure something! MAYBE A CREATURE. MAYBE CONJURE THINGS TO FILL THE TANKS! OOOOOH!
