Factual error: On the government database, Torchwood is described as being founded by HRH Queen Victoria. As a sovereign, she was actually HM (Her Majesty) not HRH (Her Royal Highness).

1 factual error in Children of Earth: Day One
Starring: John Barrowman, Eve Myles, Gareth David-Lloyd, Kai Owen
Continuity mistake: When she sees the little boy's ghost, Gwen's hair alternates repeatedly between neatly-combed and windblown/messy, depending on the shot. (00:03:30)
Captain Jack Harkness: Under normal circumstances, an exuberant Roman soldier would be my idea of a perfect morning.
Trivia: Eve Myles, who plays Gwen also plays the maid character Gwyneth in the Doctor Who (season one) episode "The Unquiet Dead."
Question: How did Jack get the Doctor's severed hand?
Answer: He might have requisitioned or stolen it from Torchwood London, or he might have been ready down below once it'd been severed, searching for "the right Doctor" and not knowing that the newly-regenerated Doctor was the one he was looking for.
