On the Island
Sometime later, Locke notices a gun on Arlen's body, so he crawls to the body and takes it. When Locke tries to commit suicide with Arlen's gun, Walt appears and tells him he has work to do. ("Through the Looking Glass, Part 1")
Later that day, Locke carries Arlen's gun to the Radio Tower, and threatens to shoot Jack if he makes contact with the freighter crew. ("Through the Looking Glass, Part 2") However, Locke fails eventually, and he leaves the Radio Tower with Arlen's gun in his possession. It is unknown what happens to the gun afterward, as it has not been seen since.
- Although the exact word is not clearly shown, Arlen was most likely security in DHARMA, as the job title embroidered on his jumpsuit begins with "Secu", and he has a gun.
- There are 3 different episodic background characters named Arlen featuring in "Through the Looking Glass, Part 1": Arlen from DHARMA, as well as Mrs. Arlen and her son from Jack's flashforward.
- The skeleton prop used as Arlen's body is also seen in "The Man Behind the Curtain" and "Cabin Fever", but it is wearing another DHARMA jumpsuit with no name or job title embroidered on it, so it is not depicting Arlen.
