Third Eye possibility

[Matt]

So im not too sure if this has been suggested but i believe that the third eye could have some connection to the Hyuuga clan's byakugan and some relevance to the cursed mark on their head just a idea

It's not even an actual eye if you look more closely.

 

[Zol]

It's no eye, it's just his symbol, the same which is on the back of his cloak or in the background when he teaches his sons...

 

[Matt]

ah ok everyone thinks its an eye
