One Part Of Doctor Who Season 15 Won't Make Sense If You Skipped Episode 5's Prequel

Doctor Who season 15, episode 5, “The Story & the Engine,” celebrates the power of stories when the Doctor makes a stop in Lagos, Nigeria, to visit his favorite barbershop, Omo’s Palace. When he arrives, the Time Lord is greeted by his old friend, Omo, who usually runs the establishment - except that the shop has been taken over by a villain called the Barber, and he has trapped Omo and the other patrons inside. As it turns out, the Barber has turned Omo’s Palace into an intergalactic ship in the form of an enormous spider that runs on stories.
