Synopsis by Hal Erickson
As punishment for helping the Avatars, Leo (Brian Krause) has his memory wiped clean and sent back into the world to start helping people all over again. Although he doesn't know exactly who he is or what has happened, Leo is still expected to make a crucial choice: either permanently remain a Whitelighter Elder or lose his powers, become a mortal, and live with Piper (Holly Marie Combs). Unfortunately, Leo is unable to assist Piper at a time he is needed most: she has lapsed into a coma after a demon attack. As she hovers between life and death, Piper experiences a spectral vision of a former love (welcome back, Julian McMahon!).
