Katherin wasn't able to catch herself when she fell, but she able to cushion the landing by building a pile of snow around her. Katherin bounced back up. She didn't have a weapon but she could make on. She danced around Kat like a boxer looking for an opening, while she created a staff made out of ice. Once the staff was solid enough toi survive a few blows, Katherin smack Kat's head with it.
