1. I know that part of the show deals with Jack's relationship with Ianto. Is Jack faithful to him, or does he sleep around like he normally does?
2. Martha appears in a few episodes, according to the IMDB listing. What is her function at Torchwood? Does she leave Torchwood, or does she simply fade into the background (meaning, she still works there, but off-screen)? Does she seem to stay there long?
3. It's implied in Doctor Who that Mickey goes off to work with Jack, at least for a while. Is that addressed at all in Torchwood? I know he never appears in an episode.
4. Do other Torchwood teams exist? Or is Jack's team the only survivor of the Battle of Canary Wharf?
5. I kind of assume that the team is based in Cardiff, and that they don't go off-world, for the most part. Is that true?
