Doctor Who’s «Dot and Bubble,» the newest episode of the BBC/Disney Plus era of Who, brings Ncuti Gatwa’s Fifteenth Doctor his grimmest challenge yet.
At first “Dot and Bubble,” the latest episode of Doctor Who, seems to be borrowing from Black Mirror’s bag of tricks. It’s set on Finetime, a planet where everyone is accompanied by a small spherical AI assistant called a Dot, which projects a “Bubble” around their heads. Within their individual Bubbles, people live their entire lives — group chatting, watching funny videos or performances by pop stars — and they do not seem to leave except to sleep. Even walking is mediated by the Bubble, telling them how many paces to move in each direction, guiding them to the office, back home, and to meals. It’s a very “kids these days and their damn phones!” kind of premise, but again: only at first.
The initially blunt metaphor only gets blunter when the monster of the week is introduced: terrifying slug aliens that are eating the denizens of Finetime alive, as they obliviously walk into their gaping maws because they can’t see past their bubbles. Our heroine for the week, the hapless Lindy Pepper-Bean (Callie Cooke), finds her Bubble’s feed intruded on by the Doctor (Ncuti Gatwa) and Ruby Sunday (Millie Gibson), who spend the episode trying to remotely lead her to safety, in spite of her skepticism.
It’s a clever setup, one that hearkens back to fan-favorite Doctor Who stories like “Blink,” and tropes beloved by writers like Steven Moffat (who, surprisingly, did not write this episode): horrible things at the edge of one’s perception, a hard limit on the Doctor’s ability to intervene, and a world engineered for conformity, with safety dependent on characters’ ability to escape societal gravity.
