The Fifth Halliwheel

The Fifth Halliwheel is the 16th episode of the fourth season and the 82nd overall episode of Charmed.

Summary
Paige feels left out as Phoebe and Cole and Piper and Leo plan to go off on their honeymoons. An innocent woman named Karen is infected with a demonic power by a Power Broker, making her confused, violent and upset. To make things worse, Paige catches Cole using a demonic power on her to find the cause of the problem, but no one will believe Paige. Cole plans to impregnate Phoebe with his evil heir but it must be done the night of the full moon, but Phoebe is distracted by the innocent. He hires a Power Broker to infect Paige while her sisters save Karen. As they go off on their honeymoons, Paige attacks Cole with her new demonic power but is eventually saved. A rift forms between Phoebe and Paige as Phoebe realises Paige attacked Cole because she dislikes him, as Karen did with her boss Elise. Phoebe takes over Karen's job at The Bay Mirror after ghost writing her column while she was infected.

Demons that auction Demonic Powers off to the highest bidder. They are known to sometimes use humans to store Powers until they are bought.

To pull a Demonic Power out of a Human Use the following Potion.

{C} In a Pot combine the following: 1 Quart of Water A dried Amaranth flower Three Pinches of Anise Seed Sprig of Boneset Burdock Root Dandelion Root 3 Drops Almond Oil

Bring to a boil and allow all ingredients to brew for hours until they have become one with each other. Add a pinch of Hyssop and steep for one-half hour. The infected one must imbibe this potion to be cured.

Notes and Trivia

 * The title is a play on the phrase "the third wheel." A third wheel is a saying used for someone who tags along unwanted. In this episode Paige feels out of place because she doesn't have a boyfriend, while everyone else is a couple. That combined with the name Halliwell becomes The Fifth Halliwheel. Charmed 4x16
 * Rebecca Balding previously appeared as 'Aunt Jackie' in the season 1 episode The Fourth Sister and this is her first appearance as Elise Rothman.
 * This is the last appearence of Becky Wahlstrom as Lila on the show.
 * When the group is at P3 at the beginning of the episode, the song "Can't Get You Out Of My Head" by Kylie Minogue plays in the background. Kylie Minogue is the sister of Dannii Minogue, who was married to Julian McMahon.
 * "Can't Get You Out Of My Head" is also a pun, as Cole is being possessed by the Source.
 * As stated by Phoebe, this episode takes place during a full moon.
 * In this episode, Phoebe wears a red choker, which will be worn by her again in The Eyes Have It. Paige wears a cream-coloured leather jacket she wore in Charmed and Dangerous and will wear it again in A Witch In Time.
 * Karen gives Phoebe her job at the The Bay Mirror and thus begins her Ask Phoebe career, eventually becoming really successful and being loved by people. In Still Charmed and Kicking, Elise mentioned that Phoebe doubled their readership.
 * We can see Phoebe's levitation allows her to almost hang on walls for as long as she needs to, she does something similar when the Crone stole her hearing; a demon attacked and she sideways jumped and dodged him. (Sense and Sense Ability)
 * At the end of the episode, where Paige tells Phoebe she doesn't trust Cole. Phoebe walks off, as well as Piper, which hints to the viewers that even though she has accepted Paige as her sister, Piper will always side with Phoebe. This will again happen in Y Tu Mummy Tambien, where Piper picks Paige to die, instead of Phoebe. This was an act, however, as Piper was planning to save both of her sisters.
 * All the sisters use all of their powers in this episode.
 * This episode scored 4.8 million viewers.

Glitches

 * The scene where Phoebe and Piper save Karen; when Piper freezes the street, you can clearly see a car backing away as the camera zooms to Phoebe. Although, Piper may have only selectively frozen the taxi that was about to hit Karen.
 * The computer monitor in Karen/Phoebe's future office changes (for money saving purposes). When you first see it, it is in the style of the old Macintosh computers, but when Phoebe is using it, it has turned into a more recent monitor in the style of Acer or any computer company in general.
 * On the DVD the episode is called "The Fifth Halliwell" rather than Halliwheel.
