Notes and Trivia[]

  • The concept of a fourth sister would be explored in season 4 when Prue dies, and Piper and Phoebe learn of the existence of a younger maternal half-sister named Paige Matthews to take Prue's place in the new Power of Three.
  • Darryl does not appear in this episode.
  • Rebecca Balding, who played Jackie, later played Elise Rothman, Phoebe's boss at The Bay Mirror.
  • The Halliwells' home phone number is revealed as 555-0198. This is also the number that appears on their TV in the season 3 episode "Sin Francisco" when Piper buys a sculpture among many other objects.
  • 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.
  • Brian Krause and Danielle Harris would work together again in the horror movie, Cyrus.
  • Kali suggested that Aviva use Phoebe as a way to get close to the Charmed Ones; Cole tried to get close to the sisters almost two years later the same way.
  • This episode scored 6.6 million viewers.
  • Future Phoebe and Paige time traveled from 2003 ("Cat House") to this episode's timeline when Piper and Phoebe were both checking out Leo.
  • This is the first appearance 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 whom he runs into briefly in "That Old Black Magic".
  • The method the sisters use to dispossess Kali from Aviva is the first and only time it's used.
  • Prue's powers are starting to grow; she is now able to close the door without seeing it.
