Piper (Holly Marie Combs) and Paige (Rose McGowan) pool their powers to prevent the coronation of the new Source of All Evil. They are still blissfully(?) unaware that the soon-to-be Source is their own brother-in-law, Cole (Julian McMahon). As for Cole's wife, Phoebe (Alyssa Milano), she has no idea that she is slated to be Queen of the Underworld; all she knows for sure is that she is pregnant, and that Cole is the father. ~ Rovi
