The Barracks in isolation.

Isolation, or loneliness, versus group cooperation in survival, was a recurring theme on Lost. Damon Lindelof has stated, "We think it's one of the unifying themes of the show--the idea that they need each other in order to survive on the Island."

Season 3[]


Jack, Kate and Sawyer are isolated on the Hydra Island

  • The Others seemed to have isolated themselves at the Barracks. ("A Tale of Two Cities")
  • Sawyer was tricked into thinking he had a pacemaker implanted that could kill him and that the same would happen to Kate if he confided in her, so he was forced to stop sharing information with her. ("Every Man for Himself")
  • Ben showed Sawyer that they were not on the main island where many of his friends were, but on a separate smaller island comparable to Alcatraz. He then quoted Of Mice and Men: "A guy goes nuts if he ain't got nobody. It don't make any difference who the guy is, so long as he's with you. I tell ya, I tell ya, a guy gets too lonely, and he gets sick." ("Every Man for Himself")
  • Mikhail said that he preferred to live in isolation. ("Enter 77")
  • Sawyer was tricked by Hurley into thinking that he would be exiled by the group for being antisocial. ("Left Behind")
  • Juliet was isolated by the group when she first came back with Jack, Kate, and Sayid. ("One of Us")
  • Jacob lived in a cabin in isolation. ("The Man Behind the Curtain")
    • However, it is not known if this was ever Jacob's home; Jacob was never seen in the cabin, and Ben confirmed he had never seen Jacob in the cabin. It would seem, though, Jacob lived alone in isolation bneath the statue.
  • Charlie died in the Looking Glass inside the equipment room, isolated in the room from the rest of the station. ("Through the Looking Glass, Part 1")

Season 4[]

  • Juliet told her therapist from The Others that the way she was treated like a celebrity maked her feel isolated; she corrected herself saying she feels "alone." ("The Other Woman")
