Mark Scout

Mark Scout and MarkS. are fictional characters and the main protagonists of the Apple TV+ series Severance, portrayed by Adam Scott.

An employee at Lumon Industries, former history professor Mark Scout underwent "severance"—a medical procedure that ensures they retain no memories of the outside world while at work and have no recollection of their job once they leave, essentially creating a new consciousness known as an "innie". Scout's "innie", Mark S., works on Lumon's "severed floor" with other severed workers.

Scott has received praise for his performance; he was nominated for an Emmy for Outstanding Lead Actor in a Drama Series at the 74th and 77th Primetime Emmy Awards in 2022 and 2025.
