BBC America is running a Doctor Who marathon and I caught a show I hadn’t seen before (I was never a very faithful fan, most of the shows I have watched have been in these marathons). This is the one with Mark Gattis as Lazarus/Scorpion man.
In the episode, a strange young man warns Mrs. Smith (Martha’s mother) twice about the Doctor and how he is dangerous. At one point Mrs. Smith says his name, but I couldn’t catch it*. In the IMDB credits he is listed as “mysterious man” (if I am looking at the right role in the credits) and that actor only appeared in Doctor Who in this one episode.
Was this ever followed up on in later episodes? It was so pointed and specific that I didn’t think this could be a throwaway. *One IMDB review says that this episode continues a “Mr. Saxon arc” but the only character named Saxon I could find in the whole series is Lucy Saxon. Is there a Mr. Saxon arc, and what was it about?
Also: early in the episode, Lazarus says to the old lady something like “our friend will get his money’s worth,” so I thought there was going to be a mysterious backer of the experiment/project that would turn out to be the real villain. Any connection to the above?
