It's the Master, disguised as Davros, who is actually Adam, in a parallel Universe populated by Sontaran Cybermen

This post contains spoilers for last Saturday's Doctor Who. If you haven't seen it by now then, well, what's wrong with you?

Being the Doctor Who fan that I am, I tend to hang around on the Doctor Who Forum. There you'll find some of the most terrifying aspects of the fandom, from people who think that the show is rubbish based solely on the fact that the current series isn't called Season 30, to people who think that Davros is actually Adam from the revived show's first series, to people who start entire threads just to post "squee" at varying lengths over and over again. It's also a breeding ground for suspect speculation, convoluted conspiracies and idiotic ideas for what people think will happen in the current series.

There have been a couple of theories bubbling to the surface this year. The dramatic reveal in last week's "The Stolen Earth" (which you can still watch on the BBC iPlayer if you're fortunate enough to live in the UK) is marginally less dramatic when you consider that a large portion of the fanbase has known about it now for very close to a year.Much of the fanbase chose to ignore this info, of course, and flat out say with absolute certainty that Davros wasn't coming back. Even when his silhouette appeared in the mid-series trailer, even when leaked photos which clearly showed him on set with a red Dalek leaked, people were denying that he would return.

Didn't stop him though, did it? I mean, it'd make things much easier for the Doctor, certainly...

Davros: I have returned, Doctor!
Doctor: No you haven't.
Davros: ...Yes I have.
Doctor: No, you haven't.
Davros: Haven't I?
Doctor: No, you definitely haven't.
Davros: Oh. Er... this is... um, sort of awkward now, really.
Doctor: It is a bit.
Davros: I'll just, um... I'll be off then, shall I?
Doctor: Prob'ly a good idea, yeah.

...but returned he has. Suck it, Portion Of The Fanbase Who Choose To Ignore The Bloody Obvious.

The other popular fan-theory over at the Doctor Who Forum is that the Master will also make a Triumphant Return, aiding the Daleks in some manner. It's not going to happen, as already apparent to anyone who is a) a fan of the classic series, and/or b) in possession of something vaguely resembling a brain. Fans are even stretching this ridiculous idea as far as to speculate that the Master is actually inside that ruddy great big red Dalek.

The annoying thing is that you can't tell 'em it's not going to happen, either. Because they take the viewpoint of "If you're not part of the NuWho Production Team, you're not qualified to say it won't happen." Apparently this means that it is happening, which is the kind of Dave Hitt Logic that jes' dun't compute.

Next they'll be trying to tell us that Donna Noble is the Final Cylon. Tch.
