Cal Kilburne

Major Cal Kilburne was a Bane, disguised as a UNIT officer.

Biography
Kilburne wanted to debrief Alistair Gordon Lethbridge-Stewart after his mission to Peru, though the Brigadier denied him. He left when Sarah Jane Smith arrived, claiming to have read most of her files, though not all, as some were level one clearance and he was only level two.

Kilburne was later at the Black Archives and met the Brigadier, who was trying to smuggle Sarah Jane and Rani Chandra inside. Kilburne stopped him and asked him to join him for dinner one day, to talk about the Brigadier's past. He then asked why the Brigadier was there, and the Brigadier told him that he was looking back on his past for his memoirs.

He returned to the CCTV command centre and found Sarah Jane stealing the Tunguska Scroll. He tried to stop Sarah Jane Smith from leaving the Black Archives with the Tunguska Scroll. Failing, he then went to find Sarah Jane at her house, but Gita Chandra found him and he told her that he was Sarah Jane's distant nephew.

When Sarah Jane returned home, he attacked Sarah Jane and her friends. Having been disarmed, Kilburne revealed himself to be a member of the Bane Kindred, posing as a UNIT officer. He attempted to eat the Brigadier, but was shot with a knock-out dart from a gun concealed in the Brigadier's cane. The Brigadier then kept an eye on him before he was taken away by UNIT.
