Fan Casting Vault Supervisor in John Carpenter's Fallout

The Vault Supervisor is the moral counterweight to the Overseer's cold tyranny. A First-Gen survivor who remembers the world before the bombs, he carries the weight of fifty years of compromise. He is proud of his son's sharp mind but knows the vault is a gilded cage. When the Overseer condemns the returning Hero to die outside, the Supervisor finally rebels—arming the populace and opening the door. He dies in his son's arms during the Mutant siege, his final words expressing pride in the leader his boy has become. He is the old world's conscience, sacrificed for the new.
