Quick and the Fourth Doctor. (TV: The Talons of Weng-Chiang)
He was married. He told Leela that while he had faced some dangerous criminals in his time, "none of them hold a candle to [his] missus in a temper." (AUDIO: Jago in Love)
Following the appearances of large metal spheres all over London, he informed Litefoot that the Metropolitan Police Service was issuing a cover story that they were a part of a stunt by a group of Bohemian artists. Litefoot raised the possibility that this may, in fact, be the case. According to Quick, the police have interviewed the Irish author and playwright Oscar Wilde to that end and were confident that he had nothing to do with it. (AUDIO: Chronoclasm) He had read Wilde's best selling novel The Picture of Dorian Gray. (AUDIO: Beautiful Things)
