We watch "Flux: Chapter Three - Once, Upon Time" (Series 13, Chapter 3), an episode so confusing that one of your hosts repeatedly named it incorrectly. (John will throw himself to the mercies of Steve and the listeners on the following episode.) Whilst said perplexion is perplexioning, Dan misplaces his date, Yaz is a bad loser at video games, Vinder gets screwed over for being honest, and the Doctor gets all fluxxed up. As one does.
