Accompanied by Tom, Pickett, Alex and another unnamed Other, they traveled across the island with Michael as their prisoner. Along the way, the five encountered Jack, Locke and Sawyer in the middle of the jungle. Tom confronted the three, and a trade was made with the recently captured Kate for their weapons. The three surrendered, and the Others proceeded back to their camp. He was later part of Colleen's team that would take The Galaga out to board and seize The Elizabeth.
Matthew was later assigned by Ben to administer an injection to Sawyer, which was used to fool him into thinking it was a pacemaker that would cause his heart to explode if it reached 140 beats per minute. The next day, Matthew and Jason escorted Sawyer as Ben took him to a clifftop to demonstrate to him that they were on a seperate, smaller island. When, two days later, Alex stormed into the work camp, Matthew was the first to be knocked down by a rock hurled from her sling shot.
After the Others' village was infiltrated by Kate, Sayid, and Locke, the Others left their home. While this was happening, a group of Others, including Mattew, donned gas masks, and took up backpacks, before gassing Kate, Jack, Sayid, and Juliet.
Matthew was later a part of the team headed by Ryan Pryce that attempted to extract the pregnant women from the 815 survivors' camp, unaware that it was a trap. He was gunned down by Jin after the first two piles of dynamite were detonated.
