A Dalek ambushed the crew of Wayfarer on Hurala. It exterminated Stella. The Dalek was frozen by a cryo-charge used by the Tenth Doctor. Its eyestalk was taken and Captain Jon Bowman tried to interrogate the Dalek but failed. The Doctor talked with it while he was alone. The Dalek's last words were that the Daleks would eliminate humanity from its very beginnings before it died, alerting the Doctor about the Arkheon Threshold. (PROSE: Prisoner of the Daleks)
