As she evanesco'd the water, Destiny watched from the Professor from the corner of her eye. She wasn't sure if Welton was only joking when she let them off the hook. She was old after all, and everyone knows old people like to change their mind whenever they please.

Like Grandmum Tole. That woman says she wants pumpkin juice and then she changes her mind and asks for firewhisky! Fickle old people.

When the Professor did finally leave, Destiny breathed a sigh of relief. She must not be that old then, since they were really were not in trouble. Stowing her wand, since the water was sorta almost cleaned all up, she looked at Evelyn when she told her to guess what she had thought of. Pfffft, Destiny was never good at guessing games, "You're thinking that instead of making a water slide out of water we should have used milk because milk makes our bones stronger and we wouldn't have had to worry about breaking something?"
