In reading Hunters of Dune, I realized that the Liet Kynes Ghola's cells should have been very hard to come by. Kynes dies in the desert in the first book, and I can't imagine there were any Tleilaxu around to harvest cells from the body as Kynes dies in an explosion of CO2 surfacing in the desert:
Somewhere beneath him, the pre-spice mass had accumulated enough water and organic matter from the little makers, had reached the critical stage of wild growth. A gigantic bubble of carbon dioxide was forming deep in the sand, heaving upward in an enormous “blow” with a dust whirlpool at its center. It would exchange what had been formed deep in the sand for whatever lay on the surface.
(p.446 of Dune, Kindle version).
So, I was wondering how the Tleilaxu masters would have gotten cells from Kynes to be stored and uncovered in Hunters of Dune? Is this a plot hole? Or is it to be assumed that Kynes' cells were merely harvested earlier when he was alive, sort of like with Miles Teg?
