After two chapters, I finally found a picture with a good look at Zane, Jay, and Nya's symbols! Hopefully I can identify them!

TADA! For some odd reason Cole's not in the picture and I couldn't figure out why. Anyway we now have a clear shot of their symbols so let's see what I can find! 

So I'm still researching the Ninjago Movie symbols but while doing that I found another symbol. 

I found Nya's Airjitzu and Jungle robes. The symbol on her hood seems quite familiar.

Remember how the one's in red are the ninja's? Well I was looking at this after looking at the symbol on Nya's robes. I'm 10000% sure that hers is a backwards H! 

That's all I've found so far because google is frustrating...(That and the fact that it's literally 12:17 at night and I'm really tired) I'll let you know when I find more!
