On September 13, 2077 Lester died after tripping behind the forklift as it was reversing. In response corporate forced the facility to post a multitude of work safety posters. All his supervisor could do is sardonically remark that their response is about how Lester wasn't wearing his hard hat and that it set their accident free day number back. The supervisor would grow to envy Lester.
Lester is mentioned only in Fallout 4.
