But why “Brogan Seth Peterson”? According to the show’s internal lore, the name was a tribute. "Brogan" was the maiden name of a producer’s high school English teacher, and "Seth Peterson" was the actual name of a key grip who saved the set from an electrical fire during season two. Our exclusive source provided a photocopy of a deleted scene from the episode "The Intervention" (Season 4, Episode 3).
