On the Island
Days 1–5 (Season 2)
Libby treats Donald after the crash in ("The Other 48 Days").
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")
