The Witch Is Back

After Prue accidentally releases a warlock that was trapped inside an old curse, she ultimately gets attacked by him. She, Piper, and Phoebe then have to call upon the witch who bound him in the curse that held him for centuries: their ancestor Melinda Warren, before he can attack them for their powers, especially after he gains a pair of unlikely allies. Meanwhile, Piper works up the courage to ask Leo out, and Andy gets frustrated by Prue always showing up at the crime scenes where bizarre occurrences take place.
