Survivors of the Flux (TV story)

Survivors of the Flux, prefixed in the title sequence with Chapter Five and in other sources with Flux, was the fifth episode of series 13 of Doctor Who. It formed the fifth chapter of the six-part serial Doctor Who: Flux.

The episode established Awsok as another incarnation of the Shobogan Time Lord Tecteun, whilst revealing the space station she was found on to be the remains of the Division with an Ood as her servant.

It further revealed the space station to be a Multiversal "Division" point in the Void between what she labelled Universe One and Universe Two, revealing that with the Flux destroying "One", all that is left is moving into "Two".
