Description: Upon their return to the present, Amelia and Rupert learn from Miss Switch's magic book that the real power behind this diabolical plot is Saturna (voiced by June Foray), the wicked witch whom Miss Switch and the children had helped to banish to the Island of Fire and Ice. As Saturna vows to get her revenge, Amelia begins to fade away and then vanishes Ð a disappearance Miss Switch knows will be permanent unless Amelia is rescued by nightfall. Amelia returns to normal just in time with the help of Thaddeus the troll, who drinks the potion which also transforms him back into the mayor. Miss Switch returns the children to school; Rupert asks her if they'll ever see her again and, as she flies away on her broomstick with Bathsheba, Miss Switch uses her magical powers to write the words "Who Knows?" on the blackboard.
