Double-Dealing
Jack and his team follow Michael into a trap where they are captured. The leader of the Others turns out to be Henry Gale. He gives Walt back to Michael and they are allowed to sail away on a boat. Hurley is also set free so that he can warn the other survivors to steer clear of the Others. As for Jack, Kate and Sawyer...well, let's just say Henry must have "Other" plans for them.
