Witches can't run away from their legacy, at least not the Halliwell sisters -- Prue (Shannen Doherty), Piper (Holly Marie Combs) and Phoebe (Alyssa Milano).
Phoebe has a strange sensation about Cole, and she casts a spell to know whether she should marry him or not, bringing unexpectedly an innocent Phoebe from her childhood and a bitter Phoebe from the future to help in her decision.
