Star Trek: Deep Space Nine, Series 4, Episode 21. First broadcast on Monday 29 April 1996. Stardate: Unknown (2372). This week, we discover to our surprise that there’s a lot to enjoy in a flawed and ultimately unsuccessful episode episode of Deep Space Nine — two wonderful guest actresses, some (largely) cringe-free sexiness, and a mature and gentle romance. Meanwhile, some TV writers imagine a just reward for their life of constant backbreaking labour.
