Love Hurts

This episode, crediting Brian Krause as the first listed guest star, marks Leo's entry into the future cast as a major recurring character. Prue and Phoebe are planning a beach weekend away from the manor, while Piper mopes about in the next room, despondent over her dating life. A wounded Leo appears the manor, asking the Halliwell sisters to protect an innocent woman returning to San Francisco under his guidance. Daisy is being stalked by a Darklighter who hunts and kills present and future Whitelighters with poisoned arrows. In Daisy's case, the Darklighter Alec broke the rules (in a way similar to Leo and Piper) by falling in love with her. Prue uses telekinesis to remove the arrow while Piper bandages Leo and criticizes him for not revealing his supernatural nature. Andy is recruited by Prue to find Daisy. Leo reveals that the Darklighters' poison is deadly, and Piper, now aware of his peril, finds a power switching spell in the Book of Shadows so she can use Leo's healing power on him. However, the spell also switches Prue's and Phoebe's powers. Piper does not know how to trigger Leo's powers and he is believed dead, but her tears trigger the power of undying love and he is revived. A weak Leo manages the stairs to meet with Daisy but that is interrupted by a new attack during which Alec manages to kidnap and orb out with Daisy. Phoebe and Prue track Alec to a deserted wood where he is about to murder her and Prue switches powers with Alec and uses his own powers against him, switching them back (regaining Phoebe's power) at the last moment before he dies.
