Notes and Trivia
thumb|300px|right|12 Angry Zen WB Trailer
 * Despite the title being "12 Angry Zen" and there being 12 Zodiac signs, only 6 Zodiacs (7 if Lo Pan is counted) are present.
 * This is the second episode, in which, all three sisters are temporarily evil, after Bride and Gloom. This time, though, it is Paige instead of Prue.
 * Novak and Dantalian are the only two demons who turned the Charmed Ones evil. Novak used Buddha's Staff, Dantalian married Prue to a warlock named Zile.
 * Piper's Chinese Zodiac Sign is the Ox and Billie's sign is the Tiger. However, Lo Pan refers to Piper as a Buffalo. In the Vietnamese calendar, the Water Buffalo replaces the Ox.
 * Phoebe Halliwell's Condo is seen for the first time in this episode.
 * Paige mentions Kazi Demons, Creepers, and Grimlocks in her conversation with Henry.
 * Just like in "The Wendigo", Piper has a flat tire causing her to meet a demon.
 * Billie finds her sister at the end of the episode.
 * Holly Marie Combs revealed in an interview that she kept Buddha's Mystical Staff and still has it in her closet.
 * Billie uses her Projection power four times; making this the episode where Billie uses the power most.

Glitches

 * The symbol on the window is identical to the symbol in the garden, but the window is seen from behind, meaning it was in reverse. When seen in the bowl it should of looked up-side-down to us.
