Trivia: For this episode, writer Peter J. Hammond borrowed his own idea - from a story he first used in the 1979 Sapphire & Steel series.

Trivia: When the team arrive at the bar, Captain John Hart (played by James Masters) comments that there is no blond in the gang - perhaps a reference to Buffy, leader of the other gang Masters belonged to in Sunnydale.
Chosen answer: As long as Jack's been in charge of it, Torchwood Cardiff has had a different agenda than Torchwood One. Tosh and Owen were there to watch for signs of the 10th Doctor, however, it was the 9th that showed up when the ship crashed in London.
