I’ve always been a fan of Ninjago, but only recently have gotten into the episodes. I’ve finished season 3 and 4 just a few days ago, and noticed a rather big plot hole.
Is there a canon explanation as to how Zane transformed into the Titanium Ninja, and how he ended up on Chen’s island in the first place? Also, is there also an explanation as to why Pixal got scrapped and also ended up on the island next to Zane?
