Jamie Burton
From Tardis Wiki, the free Doctor Who reference
Jamie Burton was a young boy who lived in Cardiff. He suffered from leukemia and was admitted to St Helen's Hospital, where he was given chemotherapy, to no success. The doctors wanted to give it to him again, which frightened Jamie, but nowhere near as much as his belief he was going to die. When Death attacked St Helen's, he tried to kill Jamie, but the boy was saved by Owen Harper and Toshiko Sato. He explained his situation, and Owen gave him an inspirational talk about how he could beat death. Owen chose to prove this by beating Death, literally, in front of Toshiko and Jamie.
