St John Colchester

St John Colchester was a civil servant who joined Torchwood Three sometime prior to 2017.

He worked closely with Gwen Cooper and Jack Harkness in the Hub in order to rebuild it and was present when Gwen brought Tyler Steele there for the first time. (AUDIO: Changes Everything)

Mr Colchester helped to investigate the Sorvix activities and insure stability in Cardiff while it was under the Sorvix rule and suffered from constant terrorist attacks. (AUDIO: Aliens & Sex & Chips & Gravy, Orr, Superiority Complex)

When he and his husband Colin Colchester-Price moved to the Ritz Towers they encountered Bilis Manger. (AUDIO: A Kill to a View)

After Yvonne Hartman showed up at the Hub and announced that she will depose Harkness and become the new leader of Torchwood, he grew to like her. He then used footage from surveillance cameras and found out that Jack secretly worked with the Red Doors, and was the first to suggest they release Yvonne from the cells. (AUDIO: Poker Face)

While working with Yvonne he started to disapprove of her cruel choices, albeit "for the glory of Torchwood" (AUDIO: Tagged), especially after she sent him and Gwen to investigate an escape room, which nearly killed them and their husbands (AUDIO: Escape Room), and later showed no sign of compassion whatsoever. (AUDIO: Herald of the Dawn) He also started to suspect that something was off about Gwen. (AUDIO: Escape Room, Herald of the Dawn)

Mr Colchester tried to contain the Rift when it suddenly became unstable. He was shot by the Sorvix assassin, who was sent to kill Tyler Steele, and was present at the Hub, when Jack realised that Gwen was not who she seemed to be, and burst of energy from the Rift separated her from the alien, that occupied her body for several months. Tyler and Orr then tried to take wounded Colchester to the hospital, while the Sorvix' god came through the Rift, but he stopped breathing. (AUDIO: Herald of the Dawn)

Behind the scenes

 * James Goss and Scott Handcock revealed that the character was pitched by Russell T Davies, who helped to develop Aliens Among Us for Big Finish Productions. His idea was to bring an older gay character in a stable relationship, the opposite of Tyler Steele in terms of personality and uncommon in science fiction. (BFX: Aliens Among Us 3)
 * Mr Colchester was intended to be Scottish, but when Scott Handcock suggested casting Paul Clayton, he and James Goss decided that he was perfect for the role. (BFX: Aliens Among Us 3)
