Gilbert (Doctor Who?)

Gilbert was an Auton. He spoke to his friend in a bar about how getting into plastics had really changed his life and before that how he had been working a "boring" job as an accountant at the BBC. As they spoke, he shot and killed a man playing Space Invaders with his wrist-gun. (NOTVALID: Doctor Who? 181)

Behind the scenes
Gilbert served a similar function as Gaz the Dalek had in previous Doctor Who? stories.
