WARNING: This article contains spoilers from Black Mirror season 7 Black Mirror made a big return to Netflix recently with its seventh season, featuring six more twisted tales of technological terror and wonder. One of the most eagerly anticipated stories was USS Callister: Into Infinity, which revisited the 2017 episode USS Callister. Fans were finally reunited with the crew of the eponymous vessel after they successfully made it out of Robert Daly’s (played by Jesse Plemons) computer and into the ether of the game’s universe.
After rejoicing at escaping and killing off their torturer, the crew members were sadly met with a terrifying new fate as they struggled to survive in this new uncharted territory. They were now reduced to stealing player tags from Infinity subscribers and desperate to find a solution to their predicament, before realising deceased crew member James Walton (Jimmi Simpson) could be the key. At the end of USS Callister, Walton sacrificed himself by restarting the ship’s engines after they got stuck in an asteroid belt while trying to make it to the wormhole.
They were also trying to escape Daly, who was hot on their tail in an abandoned spaceship. In the original episode Walton was burned to pieces by the engines, but in the new episode it turned out parts of his DNA fragments had survived and he existed within the universe. After locating Walton on a strange planet, the clone of Callister Inc.
’s CEO collected up a few prized items, including a rock with a face on the front and a hole at the back, with the implication this was a rudimentary sex toy he’d fashioned during his time in isolation. The joke involving Walton’s sex toy rock cropped up a few times across Into Infinity, however, there appears to be a potential continuity error. In USS Callister, all of Daly’s clones were lacking genitalia.
Walton explained to Cole at the time how it was part of Daly’s wholesome universe similar to his beloved Space Fleet. Walton even showed off his lack of genitalia and informed her: “We’ve tried grinding our mounds together out of sheer boredom. No sensation at all.
” Cole was furious when Daly had took away her life and her vagina and so vowed to stop him, with this being her raison d'être. Given Infinity is a wholesome universe, Walton shouldn’t have genitals even if he was regenerated and so this throws up a possible plot hole or continuity error. Then again, given the whole concept of cloning within USS Callister already requires a suspension of disbelief, this might be another one of those moments.
Moreover, perhaps when Walton was burned up and then resurrected within Infinity, he grew back his genitals and he needed a sexual outlet. Black Mirror season 7 is streaming on Netflix now.
