We're Off to See the Wizard

Phoebe shares her pregnant status with Piper and Paige just when they'd braced themselves to tell her they believe Cole is a demon somehow again. Comically, Piper sidesteps their planned discussion instead of stressing Phoebe, while Paige ham-handedly wants to bull forward with their suspicions about Cole. In the underworld, Cole's assistant Julie is revealed to be a seductress demoness planted by The Seer who has twice suggested offing Phoebe and letting the Seer work her dark magic so she can bear your heir. The Source and the Seer are constantly at odds about Phoebe, who the Seer regards as the biggest threat to the new Source, for the sources powers can be defeated by the human side of the half-breed leader. Piper, Paige and Leo team up with a magical (and ambiguous) Wizard to stop the coronation of a new Source, not realizing that the new head of the Underworld is Cole and Phoebe is his Evil Queen-to-be. Phoebe is called by the Seer who tells her that Cole needs her and she has to be his queen if not to save him than at least for their baby's sake. Phoebe choses to stay with Cole without knowing what a monster is growing in her and what are the real plans of the Seer.
