Jazz has a theory. OMG yes you get to hear the theory.

The newest character is Season 9 (Season title starts with an H)

Now the character Master of the Golden Dragon has a scar similar to Kai's

So Jazz thought "Oh it's Kai"

But she noted that they both get different spinners.

"Wait their throwing us of the trail! It is Kai but they don't want us to know!" Jazz shouted (As I was typing this)

and that is Jazz'z theory
