Artifacts

 * Billie's Book of Shadows - Billie copied useful spells and potions from the Warren Book of Shadows, and also wrote down extensive notes about their history and the evils they fought in her own Book of Shadows.
 * The Hollow - An ancient vapor and the most powerful magical force of unknown origin, which absorbs all forms of magic it comes in contact with, whether it be good or evil.

Magical Beings

 * The Triad - The most powerful collective of Upper-Level Demons. They brainwashed Christy Jenkins by letting Demons kidnap her as a child. Christy and her sister Billie are the Ultimate Power, and the Triad used them in their final attempt to kill the Charmed Ones. The Triad obligated Dumain, their jackstraw, to let the Jenkins sisters take in the Hollow.
 * Dumain - The Triad's jackstraw. He convinced Billie and Christy to do the things the Triad wanted them to do, like taking in the Hollow.
 * Christy Jenkins - Billie's older sisters. Her morality was twisted by the Triad, making her wanting to kill the Charmed Ones, as she thought they were Evil. She convinced her sister to take in the Hollow to fight the Charmed Ones.
 * Nomed and Zohar - Two Low-Level Demons. They helped the Charmed Ones with vanquishing Billie, Christy and the Triad as they knew the Triad really well.
 * Angel of Destiny - An Angel who protects the Grand Design. After the Ultimate Battle, she returned Leo to Piper.
 * Coop - Phoebe's love. He was looking for her everywhere and was concerned about her working with Nomed and Zohar.

Mortals

 * Elise Rothman - Phoebe's boss at the Bay Mirror. She was suspicious of Nomed in Phoebe's office and asked him to leave.
 * Victor Bennett - Piper and Phoebe's dad. He babysat Wyatt and Chris and made Chris orb Wyatt back to his apartment after Billie and Christy stole Wyatt's powers.

Notes and Trivia

 * This is the second and last episode with the name "Billie" on it.
 * This is the last episode in which the sisters chant a spell together on-screen.
 * The scene in which Piper cradles a dead Pheobe in her arms is an allusion to a scene in the series 3 finale All Hell Breaks Loose. A weeping Piper, as the eldest sister, cradles a dead Pheobe - the middle sister, just as Prue did with Piper when she was shot.
 * This is the last episode which shows a sequence of San Francisco views after the credits. Similar sequences have been used throughout the series.
 * Paige mentions the Book of Shadows is heavy. This could be a reference to the complaints of Shannen, Alyssa, Holly and Rose whenever they had to carry the heavy prop around.
 * Chris is coming into his powers, changing the blue card into a double red. Later he also orbs Wyatt all the way from the Manor to Victor's apartment.
 * This is Rebecca Balding's final episode as Elise Rothman. She appeared in a total of 23 episodes of the series.


 * Holly Marie Combs joked that she would sue the producers if her child (Riley) would turn out strange (handicapped) because of the final scene in this episode where she is surrounded by smoke, fire, debris from the exploded Manor; she mentioned this in an interview: "Can we get more smoke, flames, fire and gas around the pregnant woman?". Aside from being a little big, Riley is perfectly healthy.
 * During the explosion, several characters can be heard screaming.
 * Billie screaming "Christy".
 * Piper screaming "Oh my God"
 * Phoebe screaming "Oh no!"
 * When the Manor explodes and the girls fly back, they are on strings. It was said that Rose's string however was broken (which they didn't know until after the shot), which is why she was a little floppy.
 * When Piper suggests using the the Hollow before Billie and Christy do, Paige tries to remind her that when the Source and Cole used it, it drove them insane. However, the Source was shown to be going insane before obtaining the Hollow (though the sisters didn't see him until after and may not have realized that he would have had to be to consider using it) and Cole was taken over by the Source after using the Hollow and wasn't considered insane until about a year later after he'd died, returned from the Wasteland with powers obtained there, and driven mad by both them and Pheobe's rejection of him.


 * A lot of the suspenseful music used in this episode was used previously in "Long Live the Queen".
 * This episode was filmed at the same time as Forever Charmed (next episode) due to the manor scenes which had to be filmed, as well as the Ultimate Battle having to be shot twice.
 * Phoebe dies for the eighth time and Paige dies for the ninth time in this episode, making Paige and Piper tied for the sister who has died the most across the series.

Glitches

 * At the start of the episode, Billie is picking up the remains of the window inside the manor. However, the shards should be on the outside of the manor.
 * Leo's hair looks notably shorter then what it was in Vaya Con Leos. Since he was frozen and kept by the Angel of Destiny, this should be impossible.
 * When the Charmed Ones and Billie and Christy throw their potions the blast occurs before the vials hit each other in mid-air.
 * When the vials collide, Billie and Christy switch positions when they hit the railings of the stairs.

References to other movies, books, mythology, etc.

 * The title of the episode is a reference to the film Kill Bill Vol. 2 (2004).
