In the concluding half of Charmed's season-six finale (originally telecast as a single two-part episode), Whitelighters Leo (Brian Krause) and Chris (Drew Fuller), still trapped in a bizarre mirror world, must battle their evil alter egos in order to thwart Gideon's (Gildart Jackson) scheme to destroy little Wyatt. As for Wyatt's mother, Piper (Holly Marie Combs), she is just about to give birth again. But the occasion may not be a festive one: Piper is fated to be the future mother of Chris -- and woe be unto him if he doesn't return to the real world in time for his own birth! ~ Hal Erickson, Rovi
