 He teams up with Nicola and Seb, along with Faye's father Tim Metcalfe (Joe Duttine), to prove that Phelan is responsible for killing their neighbour Luke Britton (Dean Fagan) — after Seb had deduced that Phelan is the killer upon being manipulated by the latter into touching his gun, the weapon that Phelan used to kill Luke, and later finding out that Luke had been shot before dying in a vehicle explosion.Their efforts seem futile at first until Seb later tells Gary that he believes Phelan has hidden the gun at his worksite, which leads the pair to try and uncover it.However, they are surprised to learn that Phelan has actually hidden two bodies at the worksite — which nevertheless exposes the truth about Phelan killing Michael and Luke.
