Doctor Who Flux: 10 Huge Questions After Survivors Of The Flux

Some of the most entertaining scenes were with Yaz, Dan and Jericho as they travelled across the Earth in search of the date for the end of the world. Their swashbuckling Jules Verne meets Raiders of the Lost Ark exploits offered light relief, especially when meeting the hermit. But what have they actually achieved in those three years of being stranded in the 1900s?

Yaz has found the date but not the year and the message to Karvanista amounts to nothing since he cannot travel back in time to collect Dan. They might have accidentally stumbled across the answers and the means to return to 2021 when Williamson’s tunnels take him to their boat, but it does make their adventures to date seem pointless. It’s all very different from Martha’s purpose driven mission in Last of the Time Lords.

Regardless of their lack of success, two points are likely to have greater significance in the finale. The role of visionaries, like the hermit and Claire, is surely going to be key to defeating the Division and saving the universe, and the attack by the waiter with the snake tattoo suggests that the Grand Serpent is trying to stop them.
