Michael begins constructing a raft to leave the island, and finishes it after a few days. Walt secretly sets alight to it, completely destroying it. Later, Walt confesses to burning the original raft, explaining that he did not want to leave the island, but decides they need to leave. The next morning, Walt gives Vincent to Shannon before he leaves on the raft with Michael, Jin and Sawyer. That night, however, they encounter the Others, who kidnap Walt. Walt remains in captivity with the Others, but frequently appears to Shannon. In the mobisode "Room 23" it is revealed Walt posed a greater threat to the Others than they had expected, as he had been doing something unspecified that frightened them so that they would not go in to see him. Ben responds to a particular situation with a blaring alarm and people in commotion, and Juliet suggests that Ben take responsibility of the situation and bring Walt back to Michael.
