When most people can't stand to wait at the house any longer, the children show their true abilities. Sam flies to peoples' houses to check on their children, Rollo magically fixes the furnace, and Castor starts heating up (and starting) peoples' cars. But the one act that transforms most of the people in the party from non-believers in fairy tales to believers is when Mark is hit by a falling tree, and Sam lifts the entire tree off of him. Although normally most people would consider this a trick of the eyes, those at the party have seen so much that they cannot possibly deny that something unnatural is going on, despite what society may tell them.
