So maybe when Clouse found the Teapot of Tyrahn at the same time in another he wasn't. Jay undid the Skybound timeline if this theory is correct. Maybe that's why there are old villains retuning in the next season maybe they are the other outcomes of Ninjago only they found a way into the normal timeline.
