Mr. Sauer

Vern Sauer is the kind of shipmate who negotiates your surrender and his own promotion in the same breath—outraged to learn Sam was offered a hundred and fifty thousand while he only got forty, then cheerfully signing on as the Major's Prosthetic (Human) Maintenance Department Chief. He treats Arthur, the sentient typewriter, as common property to be liquidated, and his calm betrayal of an old friend is delivered with the same reasonable shrug he gives everything. Sauer's cheerful pragmatism turns the story's captivity into a comedy of manners, and his deal-making is what forces Sam to decide what loyalty to a machine is actually worth.
