Hello, I am the brother mentioned that had the theory. To clarify, given the interactions between Vasher and Denth in the end of Warbreaker and how Vasher acted when all was lost in their fight, and the distant stare kind of tired that Zahel portrayed at the end of his little spar with Kaladin...I feel like there is more reason for this as a possibility than at first glance. We know that Zahel was up to things through out the course of RoW that we have not been shown yet. Though he seems to have placed him outside of direct conflict regarding the happenings on Roshar, he is bound to have to get involved at least as much as to keep himself alive. His statement of having a "falling out" with Nightblood makes me feel that he is sincerely not too concerned with where the sword is. Looking at this from a more scientific viewpoint, Navani in her experimentation during RoW focuses greatly on music theory, more specifically pitch, rhythm and harmony. It lightly touches at one point at getting almost a fingerprint for each type of light by breaking the light though a prism and recording a spectrum of color bands. Both of these aspects of advanced senses would be greatly beneficial in the manipulation of the forms of Rosharian light. Taking this one step further, utilizing Awakenings by whispering a command at the right pitch when pushing light into a gem...this seems like a clean means to remove spren from the fabrial equation. Now to look at this from a writer's perspective. In a situation where his Breath was on the line, Zahel doesn't seem to the be the type of person to allow his Breaths to go to waste if he see's a clear benefit to their use. If he were to be forced into that choice, via his death for example, I could see this as being a powerful scene in which he levels up Navani. That being said, I would also be willing to say that at the very least the moment Navani's character learns of Breaths and what they do, she will be searching out this power like a bloodhound. It is too powerful a tool in her scholarly pursuits to deny. That's my theory at least. I really look forward to learning more about what he was up to during RoW.
