Playing his last card in a desperate attempt to please his siblings, Shendu goes to Earth once again and successfully possesses Jackie Chan. Then he travels to Australia and finds the Book of Ages, a magical book where all history is recorded. Shendu alters the book, changing history so the demons were never defeated in first place, while Jade fails to stop him, though tearing a piece of the book off in the process.
Jade then finds herself in a world dominated by demons, where humans (included her family) are slaves, and don't remember how the world used to be, since the piece of page Jade teared was about her, and thus she escaped the changes. Now Jade has to find a way to return things back to how they used to be.
This episode provides examples of:
- The Cameo: Valmont and the Enforcers are Shendu's jesters.
- The Cassandra: Nobody believes Jade when she tries to explain that demons never ruled the world. However, her electronic watch is a good proof that she was saying the truth.
- Cliffhanger: The episode ends with Shendu engulfing Jackie in flames.
- Contrived Coincidence: Jade just happens to accidentally tear out the page of the Book of Ages that is about her.
- Dangerous Forbidden Technique: Tampering with the Book of Ages to rewrite reality is considered this, to the point that even Shendu's fellow demon sorcerers are reluctant to do so.
- In Spite of a Nail: History is rewritten by Shendu to make it so he and his siblings were never sealed away and have been ruling Earth for centuries, making Earth a dystopian world with no technology. Yet, all the main characters still exist in this alternate reality, Uncle still knows how to perform Chi magic, Viper is still a skilled thief etc.
- Rewriting Reality: What Shendu does using the Book of Ages.
- Ripple-Effect-Proof Memory: Only Shendu, the Demon Sorcerers, and Jade know about the previous timeline. The bad guys' excuse is that Shendu was the one to change the timeline in the first place, and probably informed his siblings. Jade, however, escaped the mind washing of her friends because she accidentally tore out the page in the Book of Ages that stated she Set Right What Once Went Wrong. Since that section didn't get altered, neither did she.
- Sorcerous Overlord: Shendu and all his siblings are this now.
- Villain World: The point of the whole episode.
- You Have GOT to Be Kidding Me!: Jade has this reaction all over the episode; first when she realizes that the world is ruled by demons, that both she and Jackie are Shendu's personal slaves and that she has many disgusting chores like clipping Shendu's claws and the fact that Jackie has no idea of martial arts.
