To Vanquish the Swarm King and his minions
The Charmed Ones cast this spell to vanquish the Swarm King and his Minions.
- Demon swarm that serves as one,
- Vanquish him from which they come.
- Orbing: Type of Teleportation used by Leo and Paige.
- Fireballs: Used by the Swarm Demons to attack the Charmed Ones and Jason. The Swarm King used it to kill one of the many Swarm Demons.
- Molecular Combustion: Used by Piper to blow up some Swarm Demons.
- Genesis: Used by the Swarm King (not seen) to create lesser Swarm Demons from his own body.
- Shimmering: Type of Teleportation used by the Swarm Demons.
- Empathy: Used by Phoebe to deviate the Swarm Demons' fire balls. She also used it to feel Jason's emotions during a heated argument.
- Healing: Used by Leo to heal Piper.
- Astral Premonition: Phoebe received a premonition in which she saw how Mata Hari got killed.
- Sensing: Used by the Swarm King to sense where some of his minions got vanquished.
- Cursing: Used by Phoebe (possessed by Mata Hari's karma) to curse the merger. The food at the party turned into snails, frogs and doves, champagne bottles pop and squirt champagne, ... .
- Molecular Immobilization: Used by Piper to freeze Phoebe (possessed by Mata Hari's karma) and then the merger party with Phoebe (still possessed by Mata Hari's karma).
Notes and Trivia
- The WB used the promo title Mata Hari.
- Chris and Darryl do not appear in the episode.
- This is the last episode featuring Eric Dane as Jason. He will be shown once again in a hologram in Generation Hex, when Coop shows Phoebe her past loves.
- In the final scene, where Phoebe and Jason break up, Alyssa Milano said that she used her real-life emotions for that scene, because Eric and Alyssa had dated for a while and then broken up.
- The sound effect for Phoebe's empathy is different when she's using it to channel powers in this episode. It sounds similar to the jingle usually used, but is louder and more aggressive.
- This episode marks the fifth time Phoebe has been possessed.
- This also marks the second time Phoebe has been frozen by Piper's molecular immobilization, the first time was "Is There a Woogey in the House?" and the third time was in "Ordinary Witches".
- Despite claiming that she prefers to keep her work and relationships separate, Jason is the first of three guys that she dates after meeting them at the office. Jason is also not the only guy to faint when he discovers that Phoebe is a witch.
- This is the first time Phoebe receives an astral premonition from someone else's point of view and into the past.
- Mata Hari was a Dutch excotic dancer who was convicted of being a spy during World War I.
- When Leo orbs into the kitchen, Phoebe says "saved by the orb", which is an obvious reference to the popular phrase, "saved by the bell". Phoebe also made another reference to the phrase in the Season 3 episode Pre-Witched by saying "saved by the meow".
- Paige makes a remark about Phoebe walking around like she's in the nudy version of Les Miz, a French musical from the 1980s.
- When Piper first dodges a fireball from the Swarm Demon, it shows her falling with an injury on her head. However, she has the head injury before she hits the ground.
- In the beginning of the episode, when the sisters are fighting the Swarm Demons, Piper has an injury on her head, but when they orb back to the kitchen, it has disappeared.
- The spell, Aura Cleanse, has a misspelling in it. Debrise should be Debris.
- Jason tells Phoebe that she kept her magical identity a secret from him for 15 months, but they did not meet until Wyatt was three weeks old, and Wyatt will not celebrate his first birthday for another 3 episodes.
