Luke is a member of the group known as The Others. He was cleaning the grill at the house next door to Juliet's and he said "good morning" to her while she was on her way to inform Ben that he had a tumor.
After Kate and Sawyer were kidnapped by the Others and brought to the Hydra Island, Luke was put on detail at the quarry where they were put to work. He was seen talking to Juliet shortly before Sawyer kissed Kate. When this occurred, he joined Pickett in halting this action, and in doing so, he was elbowed in the face by Sawyer. Sawyer later mentioned to Kate that Luke had some form of martial arts training.
Luke 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.
