On the Island
Days 1–5 (Season 2)
The tail section tore off and landed on a different side of the Island than the plane's middle section. After crashing into the ocean, Donald dragged himself out the water and was helped by Ana Lucia, who, however, left him when she saw that Emma was in danger of dying and needed to be revived. Donald suffered from a major leg fracture due to the crash; it was Libby who put the bone back in place, though Donald passed out because of the pain.
However, Donald succumbed to his injuries five days after the crash, due to an infection of the injured leg, and became the fourth death among the tail section survivors. He was buried by Nathan and Goodwin. Though his burial is visible in the episode, it can be seen more clearly in an ABC promotional still. ("The Other 48 Days")
Libby referenced Donald's existence as proof to Hurley that the Island was in fact not a mere fabrication of Hurley's imagination. ("Dave") Later, the moment after flight 815 crashed into the ocean was seen again during Eko's dream, and Donald was seen struggling in the water briefly. ("?")
