Reviews
Gerard O'Donovan of The Telegraph gave the episode 4 stars out of 5, saying "for the first time since its opening episode Humans really got to the heart of what good science fiction does best": "making us reflect on the human condition." O'Donovan opined that "the only disappointment was that last week's big reveal – that detective Karen Voss (Ruth Bradley) is a synth hiding in plain sight – failed to be developed in any significant way this week."

Neela Debnath of Express said that "episode five serves as more of a developmental instalment than anything else", and described the series as "basically like an unofficial sequel to Blade Runner that we've been wanting to see for a while." Cameron K McEwan of Digital Spy said it was an "engrossing instalment" and "incredible episode", raising both plot-related and ethical questions.
