Doctor Who Flux: 10 Huge Questions After The Vanquishers

10. Is The Universe Still Mostly Destroyed?

The Flux is effectively obliterated by the bigger on the inside Passenger. Matter and anti-matter destroy each other on contact. All well and good, if we can overlook the slightly dodgy science, but how come the potentially infinite matter contained within a TARDIS didn’t have a similar effect? Perhaps because the Doctor tried to defeat it with time rather than mass? Maybe she should have kept the door shut at the end of The Halloween Apocalypse.

More importantly, this was supposed to be the Flux’s final assault on a universe it had already mostly destroyed. So what’s left? Has time been reversed, is the universe back to how it was before the Flux was released? Something must have changed because the New Year special sees the return of the Daleks, despite their entire fleet being wiped out by the Sontarans.

It’s possible there are reconnaissance Daleks taking shelter somewhere on the shielded Earth, ready to make our planet the new Skaro. And let’s not forget the Williamson tunnels, which for some inexplicable reason are gateways between different worlds and times. It’s another convenient way for them and all manner of other alien invaders to resurface.

Unless the Doctor is planning to take Yaz and Dan to a new universe, leaving Karvanista, Vinder and Bel to pick up the pieces, this one will still need to be fixed. Russell T Davies won’t want to be saddled with a series tied exclusively to Earth and a bunch of unpopulated wastelands.
