- For "Messages from the bottle", see: The Lost Symphony
The message bottle was carried on the second raft and contained messages from the castaways. This idea was conceived by Charlie who asked various Losties for messages. ("Exodus, Part 1") Several were read by Sawyer while on the raft, including Tracy's and "Hugo"'s (not realizing that it was Hurley's). ("Exodus, Part 2") Below is a short transcript:
SAWYER: Yep. I, for one, never knew how much Tracy missed her hubby and 2 kids back in Fresno. Yet she's sleeping next to good old Scott to keep her warm at night.
WALT: That's Steve. Scott's dead.
SAWYER: Whatever. It's alright, Kazoo, we've got to keep ourselves entertained. Who the hell is Hugo and how's he got a 160 million dollars to leave to his mom?
WALT: How would you like it if I read yours?
SAWYER: You can't read mine because I didn't write one.
WALT: Why not?
SAWYER: Because the only one I ever wrote is to the man I'm going to kill.
The bottle washed up on the shore and was found by Claire and Shannon, who gave it to Sun. Sun buried it to keep the rest of the castaways hopeful, and accidentally buried her ring at the same time. ("Everybody Hates Hugo") Sun later told Kate about the bottle. Kate poured out the messages to find Sawyer's. She then noticed Sun's ring in the sand. ("...And Found")
- Bottled messages usually feature in stories or jokes about castaways. It is a common cliché in such stories.
- In the Police hit song "Message in a Bottle", it's a metaphor for the struggle to break isolation and communicate. The marooned character launches an SOS, then one morning finds "a hundred billion bottles washed up on the shore", from "a hundred billion castaways looking for a home", and concludes: "Seems I'm not alone in being alone."
- Letters from the message bottle were read aloud by various cast members during the Lost Live performance at UCLA's Royce Hall on May 13, 2010. According to Damon Lindelof and Carlton Cuse, both present at the event, the letters were prepared by the show's writers in Season One and are written from the perspective of various "nameless" survivors of Oceanic 815.
