I been thinking that since is very probably that Adolin is going to be able to revive Maya, I kind of think that somehow Navani is going to do the same with The Sibling in the tower, and she is going to become the second Bondsmith. I think that the high focus we are getting from her PoV, and how persistent she is being about finding out the secrets of the tower is building up to this.
What do u guys think about this?
