Used to the cold weather as an ex Durmstrang student where the weather in the winter was much more drastically, Mason entered the charms classroom while unwrapping his Ravenclaw scarf from his neck. He put it in his schoolbag as he walked inside behind a few of the other students.

The room was warm, the professor must have used a heating charm in the room.When he looked around to find a place to sit, he heard one of the girls (Dora) greeting the professor as 'marching band' The fifth year laughed which he successfully disguised as a cough a second later before nodding his head to the professor "Good morning, Sir"
