As the result of a misbegotten spell cast at her high-school reunion, the "present" Phoebe (Alyssa Milano) disappears, replaced by her former teenage-delinquent self. Making matters worse, this younger, wilder Phoebe intends to use her magic skills for all the wrong reasons. This turn of events is particularly painful for Paige (Rose McGowan), who now wishes she'd never asked what Phoebe was like back in school. Meanwhile, Piper (Holly Marie Combs) consults her dad, Victor (James Read), to find out why Chris (Drew Fuller) is avoiding her. ~ Hal Erickson, Rovi
