@@asdfdsdfasfsfad1 No, Jadeite was trying to save Jade and purify his lapis, but also ended up going along with his plans to create a new world. Jade's lapis itself was corrupted and sentient, and its influence eroded at his mind and body. So Jade's lapis was the one controlling him.
This sounds like zelle dubstep and it's amazing. Honestly the best of my favorite pop'n music songs in my opinion. Imagine in Zelle 2 you have to fight Emerada from the original zelle and this played, I would freak out. I dont know if Xion (the music producer for the original zelle) can make dubstep but this is fire.
