"Erm, well, Peskipiksi Pesternomi is the incantation for the freezing charm," Anna said. "I suppose that would do the trick. If you believe Gilderoy Lockhart, that is. Anyway, the correct incantation to the Freezing Charm would freeze the water we shoot from our wands, at least." Anna smiled at the thought of freezing the entire corridor with ice. It'd be fun to see who would stroll on by and unexpectedly play a game of slip and slide. Hopefully it wouldn't be her Cale, though. She would never want to hurt him... Anna watched the professor, waiting to see what he'd do next. She was ready to get this show on the road and see what type of chaos she and the rest of the little group could create! No way would they get into trouble for this! They were with a professor! That would help them if trouble came their way...right?
