Irving Bailiff, known as Irving B. when working at Lumon, is a macrodata refiner at Lumon, who worked there for six years before agreeing to undergo the severance procedure, where his consciousness and memory are divided into two parts. The most devoted of the MDR team, Irving clings to Lumon’s rules and rituals. His Innie is deeply loyal, while his Outie is an introspective, artistic man with a buried past.
