As a result, Paige is erased from existence of her sisters, Phoebe is living the high life as Cole's wife even though she doesn't love him, and Piper is on a demon hunting frenzy to avenge Prue's death and is no longer married to Leo. When Paige tries to reconstruct the Power of Three in order to vanquish Cole, Phoebe is the one who actually vanquishes him, and as a result, all of Cole's spell on the Charmed Ones is undone with one drawback: Paige is the only one who remembers what happened.
