Artifacts[]

Terms[]

  • Blue Moon: A a phase that traditionally loosens the bonds of magic, on the three days when the blue moon rises. It can wreak havoc with all magical forces, causing witches' powers to become erratic and unpredictable or even ineffective.

Notes and Trivia[]

  • The WB used the promo title Blue Moon.
  • The WB use clips of the big bad wolf from "Happily Ever After" in their trailer for this episode.
  • Instead of using makeup effects, computer generated effects were used for the beasts, which cost less money.
  • Piper previously transformed into a beast under the full moon in "The Wendigo".
  • In this episode, it's hinted that Magic School is located somewhere near the Golden Gate Bridge, as the sisters look through the windows and see it. It is also believed to be floating in the sky.
  • This is the third time that Piper actually refers to Leo as her husband, while talking to the Avatars at the end of the episode. The first time was Siren Song and the second Time was Oh My Goddess! Part 1
  • Phoebe does not receive a Premonition.
  • This marks the sixth and final appearance of Nick Lachey as Leslie St. Claire.
  • This is the first time Piper uses her powers without her hands and only her mind. She claims that she was angry and reminds us that their powers are tied to their emotions.
  • Phoebe's premonition powers seem to be affected by her extensive sadness/sensitivity. This is the second time Phoebe's visions were affected by her emotional sensitivity, the first time was A Witch in Time where she was emotional attached to Miles.

Cultural References[]

  • The title is a reference to the term "Once in a blue moon", which refers to something happening very seldom.
  • The sisters transforming under the Blue Moon is similar to the fictional portrayal of werewolves transforming under the full moon, similar to the Wendigo.
  • The ice cream Paige is eating is Ben & Jerry's Phish Food which is known to be Rose McGowan's favorite in real life.

Continuity Errors[]

  • When Piper is about to explain about Leo, Paige orbs ice cream to the table she starts to take off the lid, but in the next shot she has the lid off and is eating it already. She also asks for three spoons, but only one spoon is shown.
  • When Phoebe talks to Leslie about him leaving, her arms change between shots from hanging by her sides to her hands clasped together in front of her.
