Leaked evidence suggests that an upcoming episode of Doctor Who will be shot in the u.s.
But that’s not the possible spoiler. The possible spoiler, if actual, is fairly big, so I’m consigning it to the comments section. Proceed at your peril.
SPOILER WARNING:
The episode in question is rumored to be based on Terrance Dicks’s novel Blood Harvest, which according to Wikipedia features, inter alia, the Doctors’ fellow timelords Romana and Borusa.
That doesn’t mean, of course, that an episode based on the novel would feature them also. Apparently there’s a lot else going on in the novel too (locations include both 1920s Chicago and a planet of vampires). So there may not be much of a spoiler here at all. Or there may. Time (appropriately enough) will tell ….
I didn’t read the above comment, but why would you even read a site called Doctor Who Spoilers? Do you really want to spoil it?
