The Twins were two identical men who accompanied Tom and the Molotov woman when they kidnapped Walt from the raft. The significance of these twins and the Others on the boat is that this is the first time the survivors have seen/encountered the Others, excluding Ethan. The Twins were a nonspeaking roles that occurred only once, and were played by extras who were stuntmen.
After a brief conversation with the survivors on the raft, Tom declared they were going to take the boy. After Michael furiously refused and Sawyer grabbed his gun, the boat's lights were shut off, and the Others attacked. ("Exodus, Part 2")
- In a interview with Buddy.tv Damon Lindelof said he remembered that they hired the twin stuntmen to be guys on the boat, but they were never meant to become important to the storyline at a future date. "We can tell you, sitting here now that twins have nothing to do whatsoever with the mythology of the show."
