How would Toneri even know about the Jougan though? Hamura's moon branch family had no contact with the main Otsutsuki clan.

It seems to me that the Jougan is Boruto's inborn Otsutsuki skill. And Toneri somehow figured that out beforehand. I hope it's a completely different dojutsu and not just another amalgamation of the Sharingan/rinnegan.
