Biography
Sean used to serve in Iraq with Ty and Choo-Choo. After the war ended, they joined Avery Markham's gang, where Sean gained the nickname "Seabass".

In the episode "Cash Game", Seabass is briefly seen at the pizza parlour when he orders US marshal Tim Gutterson to leave. he later appears again entering the house belonging to John-O Hutchins and his wife Betty, with it later being revealed in "The Trash And The Snake" that he and Ty killed them for insulting Ty and refusing to sell their house to Markham.

Seabass is next seen in "Noblesse Oblige", when he and Choo-Choo kidnap Boyd Crowder and bring him to Markham. As Boyd leaves after being intimidated by Markham, Seabass threatens him.

In "Sounding", Seabass discusses with Ty and Choo-Choo the fact that someone is interfering with Markham's plan and conclude it's either Boyd or US marshal Raylan Givens. Ty later sends Seabass and Choo-Choo to interrogate Calhoun Schrier, but during the interrogation Choo-Choo punches Calhoun in the head and kills him.

Seabass appears at the beginning of "Alive Day", when he and Choo-Choo decide to call Ty and tell him that Choo-Choo killed Calhoun. Ty arrives at Calhoun's office and Seabass realises that Calhoun's prostitute Caprice saw them enter. Seabass initially offers to go after Caprice, but Choo-Choo ultimately decides to do it in order to clean up his own mess.

Markham and Seabass receive a call from Ty in "The Hunt", with Ty, who was shot in the shoulder by Raylan at the end of "Alive Day", requesting that they send someone to extract him from the church where Caprice was held and where he claims to be holed up. However, Markham figures out that the cops have stormed the church and Ty is trying to get his men arrested. Markham pays Seabass to stay loyal.

However, this doesn't work, as in "Burned", Seabass shows up at the hotel room where Katherine Hale is staying and holds Katherine and Markham at gunpoint demanding money. Katherine manages to trick Seabass into letting her reach into her purse and fires a handgun hidden inside, hitting him in the leg and bringing him down. Katherine then finishes the injured Seabass off by shooting him in the head.
