The 2022 Doctor Who Yearbook includes interviews with Jodie Whittaker (the Doctor), Mandip Gill (Yaz), Craig Parkinson ("the Great Serpent" speaks about the art of villainy) and a host of Flux guest stars, plus behind-the-scenes features and more. Find out about dog days with Craige Els.
The last chapter of Flux was proven to be.. a massacre. I can't say it was not unexpected, during an event that involves the destruction of the entire Universe some victims are expected to happen. There were some good moments, too. Only some, but good - the rate of the episode was a medium one (it was not bad, but it was far from something extraordinary).
And Tecteum returns in Doctor's time briefly (only in this episode) and unexpectedly: as Division chief she is the person accountable for the appearance of the Flux and for trying (more or less successfully) to destroy the Universe. The moments the two women spend together are at least interesting (and almost shadow the rest of the action): the Timeless Child could have come from another Universe and Tecteum tries to get there after she smashed her original Universe. She has the Doctors memories and it's only a problem of time (almost a week, for us) until she is going to get them back.
