Yueh, who performed the kidnapping of Leto under duress, arranges for Jessica and Paul to escape into the desert. Duncan is killed helping them flee, and they are subsequently presumed dead in a sandstorm by the Harkonnens. Yueh replaces one of Leto's teeth with a poison gas capsule, hoping Leto can kill the Baron during their encounter. Piter kills Yueh, and the Baron narrowly avoids the gas (due to his defensive shield), which kills Leto, Piter, and the others in the room. The Baron forces Thufir to take over Piter's position by dosing him with a long-lasting, fatal poison and threatening to withhold the regular antidote doses unless he obeys. While he follows the Baron's orders, Thufir works secretly to undermine the Harkonnens.
