Fuller asked a question and young Coop was one of the first to answer. Or well, propose a question. Huh. His blue eyes widened as he mulled over the question. Yes, it was a good question. He nodded in agreement with Coop, Cutty, Sophie, and many others. Cutty's answer was rather intriguing. Now other ways that they could stay warm. Transfiguration could help them? Potions could help them? He mulled over these thoughts and nodded when Sophie added her point about how the insulation spell could stop the snow inside the castle. "Professor, I'm not sure if this possible but could we use an atmospheric charm to try to stop the snow from falling in the castle?" he asked, not knowing if this would actually work. Oh well. Just a guess then.
