Cat House

Cat House is the 106th episode of Charmed.

Episode Guide
A woman, Katrina, is feeding her cats when a warlock blinks in. She senses him and attacks in self-defense. Blinking behind her, she turns around and he cuts a necklace off her neck, but she kicks him down and signals the cats to attack him. Katrina escapes but the warlock fights off the cats and he picks up her necklace. It bears a triquetra.

Paige and Phoebe are talking about Piper's past relationships. Leo and Piper are arguing. Leo is walking away and Piper accidentally blows up a door in her anger. This worries Paige and Phoebe. Phoebe and Paige try to help them work it out. But Leo insists that it's not their problem. Phoebe schedules Leo and Piper to see a mortal marriage counselor, with Paige explaining that their problems are marital, not supernatural. They both agree.

The warlock is looking through a drawer when he finds a scry crystal and a map. He scries for Katrina and finally the scry crystal lands on a location.

Paige goes to Phoebe's work and tells her that she's been worried about Piper and Leo. Phoebe agrees, saying that she's been feeling the same way too. But she reassures Paige that they've been through a lot worse. Katrina calls Phoebe and says a warlock is after her. She is in the manor, asking for her to come home with her sisters and Leo because she has a cut across her neck, and she needs healing. Leo, however, is with the marriage counselor.

Leo and Piper talk with the marriage counselor. They have mostly awkward silence, until Piper freezes the marriage counselor. Piper casts a memory spell and unfreezes the counselor.

The warlock tracks Katrina to the manor, but Paige and Phoebe orb in. Paige orbs Katrina away while Phoebe fights the warlock. Phoebe gets the upper hand, but she, Paige and the warlock suddenly find themselves outside the manor. The warlock blinks away.

As Leo and Piper retell their past experiences in an effort to rekindle their love for each other, Phoebe and Paige find themselves watching those same experiences play out. They flash from one scene to another as Piper and Leo continue to talk. They flash to the scene of Leo and Piper's wedding (Prue briefly appears in this scene in footage reused from Just Harried), and after Kit, their cat, comes up to them, the warlock blinks in. He seems as surprised as Phoebe and Paige and quickly blinks away again. Phoebe and Paige fear that the warlock has altered the past. They soon figure out that all they are seeing centers around Leo and Piper, and that they've somehow been pulled into a time loop.

The warlock blinks in again and Phoebe and Paige realize he's after Kit (who had run away some years ago). After reading the Book of Shadows entry on familiars, they realize that Kit had been their familiar. After several more flashes--including the one in which Leo proposes to Piper--they hear Kit yowling. Paige orbs and find the warlock has just stabbed Kit. Kit's corpse morphs into that of Katrina. In the present, Katrina disappears. Leo develops a sudden headache; he's feeling the pain of hundreds of witches. Piper freezes the marriage counselor and strangely hears Phoebe calling to her from the past. Phoebe wants Piper to go back to when Leo proposed to her. This time Paige and Phoebe are ready for the warlock. Phoebe stabs the warlock, vanquishing him.

Katrina has reappeared and reveals that she had been Kit, and that she'd left because her work with the Charmed Ones had been complete. Leo says that the Elders had made her human to guide other familiars--a reward granted to only a few special familiars. He also reveals that the pain he'd felt had been those of the witches who'd lost the familiars Katrina had been training when she'd been killed by the warlock. Piper and Leo vow to spend more time together.

Spells

 * 1) The Feline Warlock scrys for Kit.
 * 2) Piper casts the Spell to Relive Memories

 * Paige's necklace is removed during the orbing scene
 * In They're Everywhere it is said that warlocks don't bleed. However Katrina draws blood when she scratches the warlock's face in this episode.
