When Paige gets knocked down by the zodiac she falls in the living room. Later when Phoebe comes home Paige is now in the family room where the fireplace is. No one has moved her so why is she shown in another room?
Phoebe tells Paige that in order to find Piper, they have to use the To Call a Lost Witch Spell, but Paige tells her that it would not work because Piper isn't lost, despite having using this spell to summon each other many times before.
Despite twins Jason & Kristopher Simmons (Wyatt Halliwell) being listed in the end credits, they did not make an actual appearance in this episode.
TRIVIA: Starting with this episode, twins Jason and Kristopher Simmons are now listed as Wyatt. They are listed as recurring stars for the rest of this season, even if they don't appear in each episode.
The "Eternity" symbol is written on the laundry store's glass window...but it's written so it faces inward. Anyone outside would see it backward, making it meaningless.
As established, this episode takes place on January 29, the Chinese New Year, but in the season 8 episode "Payback's A Witch", they celebrated Wyatt's birthday, which as stated in the season 5 episode "The Day the Magic Died" takes place on February 2nd (which was two episodes ago).
TRIVIA: When Billie uses her Projection power to find her sister, not long after she was kidnapped, she comes to the conclusion that Christy was kidnapped for the powers, she didn't know she had.
The bridge in the garden was the same one used in the season 4 episode "Enter the Demon". It was the bridge in Limbo over which you had to cross to get to the afterlife.
In the beginning of this episode, Piper talks about how she was unable to go with her boys to Marineland, but later in the episode when she is trying to get Phoebe to help with Buddha's staff, she calls it Marineworld.
TRIVIA: There are 12 Chinese Zodiac signs per cycle with only half of them making appearances in the episode but only 5 are visibly identified, namely the Rooster, Dog, Rat, Snake and Dragon.
TRIVIA: With the help of Lo Pan, Billie manages to temporarily control her new power, Projection. It helps her see her sister Christy, turn the Halliwell sisters from evil back to good and then, while holding it, becomes in tune with the Zodiac staff, to vanquish the demons who are after the staff.
TRIVIA: Piper is given the Zodiac staff to protect, until the ceremony is held to pass it on to the next Zodiac, not realizing that it takes the emotions & obsessions of the holder and passes them to others.
Lo Pan, the drycleaner/monk, says that Piper is a Buffalo, meaning she was born in the year of the Buffalo. But in the Chinese Zodiac, there is no year of the Buffalo - but there is the Ox.
TRIVIA: Chinese New Year is the subject of this episode, which was celebrated two weeks earlier, on January 29, 2006, making it the Year of the Dog.
