Really, given how the situation played out... it doesn't seem all that surprising that M'rahz is taking M'zhet under his wing. Not as a Nunh, but as the leader of the tribe. He's thinking to the future of it, and he sees Zhet's tenacity and resolve as potentially good traits to have. However, Zhet also needs the strength to claim the title of Nunh and then hold onto it.
What's interesting to muse on, however... that even if Zhet does ultimately succeed and claim the title of Nunh from Rahz, Rahz could technically still serve in that leadership (or, at least, an advisory) position while still a Tia. After all, with the apparent respect Zhet has for Rhaz now, I'm pretty sure their final challenge won't result in death or exile or anything like that. So, rather than having double-duty like Rahz has now, Zhet could handle the Nunh duties while Rahz carries on being that inspiring leader.
That honestly would be an interesting tribe to see, really. One where a Tia is effectively the leader, but is not the best choice for Nunh. The other option, of course, is that there is a Seeker matriarch who is the leader. Or perhaps even a council of elders sort of situation.
