We watch "Flux: Chapter Two - War of the Sontarans" (Series 13, Episode 2) where the Doctor and the Newby Crew are all transported to the Crimean War in the 19th century... until some of them get honorably discharged to parts elsewhere. Whilst the Doctor remains on the front to battle the historically inaccurate Sontarans, Dan returns to present day Liverpool to whack said Sontarans with a wok, and Yaz has a meet-cute with new companion (?) Vinder… until those two are captured by the season’s big bad. Worst. First. Date. Ever.
