Willow defends her use of magic in a line that was cut due to length: "But it's good-witch power, not bad-witch power. You know, Glinda-in-a-bubble power, not Margaret Hamilton-on-a-bicycle power."
When Dawn and Buffy enter The Magic Box early in the episode, Xander is reading an X-Men comic book. The issue, X-Men #109, is the last in that series before the death of Colossus - an event which later became pivotal to Joss Whedon's run on Astonishing X-Men.
Leland Crooke (Professor Lillian) also plays a recurring character, the demonic Archduke Sebassis, in Joss Whedon's spin-off of this series, "Angel".
The wall painting of the women in Glory's mansion, is a reproduction of a painting "Group of Four Nudes" (1925), by Tamara de Lempicka.
Xander says: "It's Dawn Giovanni and the Buffster". He is making a reference to Don Giovanni, the opera composed by Mozart, first performed in Prague in 1787.
