In this crossover episode with Boy Meet World's "T.G.I.F" neighbor Sabrina the Teenage Witch, Eric (Will Friedle) suspects that Jack's weird new girlfriend Millie (Candace Cameron-Bure) is a witch. Outraged, Jack (Matthew Lawrence) tells Eric that their friendship is over. Ironically, by the time the pals have made up, Eric is himself dating a certain Sabrina Spellman (Melissa Joan Hart), the "teenage witch" from the series of the same name. Meanwhile, Cory (Ben Savage) tries to help Topanga (Danielle Fishel) overcome her fear of flying--with unexpected results. ~ Hal Erickson, Rovi
