Nothing is known about Gareth's life before or as the outbreak began.
Gareth appears in the large room that Carl, Rick, Daryl and Michonne go inside of after sneaking into Terminus. Gareth questions them, asking if they are there to rob them, which they respond to and then if they are there seeking sanctuary. He orders them to drop their weapons and Alex frisks them. Gareth warns the four of them not to try anything stupid and has Alex show them around Terminus. Rick, after noticing the Terminus members possessing several items belonging to members of the prison group such as Daryl's poncho, Hershel's pocket watch, the riot gear, and the orange hitchhiker's bag, Rick takes Alex and holds a gun at his head demanding to know where their people are and why their group has the pocket watch, riot gear and poncho. Gareth lies, claiming to have taken the riot gear off of a dead cop and that they found the poncho on a clothesline. After a Terminus Resident accidentally shoots and kills Alex while aiming at Rick, a shootout ensues and Rick, Carl, Daryl and Michonne flee, only to be stopped when Terminus residents line up along the outside of the fence at the back entrance with guns pointed at them. Gareth orders the four of them to lower their weapons. After this, Gareth calls them by specific code-names to walk towards the boxcar: Rick (Ringleader), Daryl (Archer), Michonne (Samurai) and Carl (Kid) in that order.
