Sayid and Shannon became friends in season one. Boone told Sayid to stay away from Shannon, but Sayid didn't listen. After a romantic outing down the shore. In the second season, he built Shannon a tent, where they made love. When Sayid left to get Shanno a drink, Walt appeared. Shannon screamed, and Walt was gone when Sayid came. Sayid didn't believe Shannon, and she became determined to find Walt. Sayid followed her into the jungle, where they saw Walt. Michael, Sawyer, and Jin showed up with the tailenders, and Ana-Lucia thought Shannon was an Other. So she shot her, and Shannon died.
