When Leo warns her that once Phoebe has taken a life she will be a Banshee forever, Piper summons Cole/Belthazor. She figures that he can retrieve Phoebe by convincing her that he still loves her. However the plan goes awry when Banshee Phoebe picks up on Cole's own pain and tries to kill him! Cole gets the upper hand in the ensuing battle but is unable to kill her because of his love and tells her so. Phoebe is restored to her normal self. Cole says he cannot get over her and tries to explain his killing of Jenna (see Exit Strategy) by saying that Raynor had put a spell on him. Then he shimmers away.
Later at P3 Phoebe tells Piper she made a mistake giving up on Cole, that there's still good in him, and she thinks she can bring him back.
