Jodorowsky's Dune Uncovered
Scene 115 : Kynes's Death
Kynes is wandering in the desert, exposed to the bright sun with only rags of his uniform to protect him, but no stillsuit.
He has a vision of the young version of himself, dress in the suit he wore when he arrived on Dune. (See Part 2)
As the young Kynes talks about the plan to transform Dune the old Kynes kneels down and plunges his arms into the sand looking for humidity.
The young Kynes explains that beneath him the spice is fermenting - "Little worms are beginning to lose their water in the solid mass.. the carbonic gas is going to explode..."
Suddenly a blue sphere of prespice mass emerges from the sand, envelopes him and then explodes killings Kynes.
The Moebius storyboards appear to have removed Kynes's vision of his younger self, but keep his death by the Spice explosion as in the novel.
