The Tensigan is an evolution of Byakugan, unlike Rinnegan who is an independent Doujutsu of the Sharingan, so I was thinking, would Hanabi be able to demonstrate the ability to activate and to deactivate the Tenseigan at some point in Boruto, because the Kakashi was able to activate and to deactivate the Mangekyou which is an evolution of the Sharingan. At the end of "The Last", the Tenseigan was deactivate (I believe that because Toneri had no more chakra to maintain it, just as Mangekyou also deactivates when there is little chakra), that is, only was turned off. In the Naruto series when a Doujutsu is awakened it can even be deactivated, but be UNDONE (cease to exist) never happened, I think it's impossible. That is, the Tenseigan is in Hanabi's eyes, but deactivated.
