Wicca Envy

S1 E10: Rex and Hannah set out to destroy the sisters Halliwell and frame Prue for murder while angering her by Rex dating Phoebe. The girls learn the only way to get Prue out is to agree to conjure a spell which would relieve them of all of their powers, forever. Mysteriously, though, they get their powers back with the help of Leo, the handyman and the sisters' guardian angel.
