 * Come to me, Kali,
 * I conjure thee, Kali.

 * Darryl does not appear in this episode.
 * Rebecca Balding, who played Aunt Jackie, later played Elise Rothman, Phoebe’s boss at The Bay Mirror.

 * It appears that Aviva had latent witch genes which were just beginning to show themselves. She only had basic witch powers (such as spellcasting) before Kali granted her powers. Additionally, when Piper froze the room, Aviva stayed unfrozen.
 * This is the only time that Piper refers to Grams as grandma.

 * This is the first apperance of Fireballs in the series
 * In Phoebe's premonition of Prue getting attacked, everything is black and white except for the fireball, this could be due to the fact that it was a magical attack.
 * This is the only episode in which Leo and Andy ever encounter each other. This notes that other than Phoebe and Piper, Leo is the only person to encounter every regular character throughout the series, including Jenny Gordon.
 * The method the sisters use to dispossess Kali from Aviva is the first and only time it's used.
