What's more, Awsok seems to know an awful lot about the Flux, what caused it and what it true purpose is: "The Flux event was spatial," she explains, adding that the Ravagers were freed as a "temporal contagion" to ensure both space and time were disrupted. Played by Barbara Flynn (Cracker, Cranford), she appears to know the Doctor – another old friend/foe from her days with the Division? – and doesn't seem at all surprised when the pair meet again. But what, and why? Is it the result of something our Time Lord hero did recently, or is it another consequence of her forgotten past coming back to bite her? Who is Awsok?

So there we have it – the Flux was man-made, it's a force that's being directed by some higher power, and somehow its a response to the Doctor's actions. how is the Doctor responsible? "The Flux wasn't an accident – it was made, it was placed… because of you," says Awsok. So far, we've been asking "What caused the Flux?" – now we know the answer, sort of, and our next question is.

Having been pulled out of her own timestream, the Doctor (Jodie Whittaker) takes a brief detour before reuniting with Yaz (Mandip Gill), Dan (John Bishop) and Vinder (Jacob Anderson) in the temple of Atropos – she awakes in parts unknown, accompanied by the mysterious Awsok (Barbara Flynn), who drops a rather large bombshell.
