Here Walt is kidnapped by the Island's previous inhabitants, the Others, and Michael spends his time trying to retrieve him. He is eventually successful, and they leave the Island together, but the guilt over the murders he had to commit to achieve this leads him to an estrangement with his son and a suicide attempt.
