Timmins

 was a pilot. When his planet was attacked by the Daleks, he was assigned to help Captain Tillyard evacuate the town of Cami. On the way to the planet Credence, he discovered that the captain intended to turn the refugees over to the Daleks. He told the Third Doctor and Jo Grant, and when they landed on Credence, the captain was killed. The Doctor convinced Timmins to take the ship, which was low on fuel, out of orbit to rendezvous with the other refugee ships. Timmins survived, but never told anyone about the presence of the Doctor and Jo, who had escaped the ship in their blue box. (PROSE: Hide and Seek)
