Star Trek: Deep Space Nine, Series 3, Episode 5. First broadcast on Saturday 24 December 1994. Stardate: Unknown (2371).

Stardate 46519.1: Surgically altered to appear Romulan, Marina Sirtis wakes up on board the Romulan Warbird Khazara looking as fabulous as she has ever looked and starts threatening an increasingly cowed Carolyn Seymour. The result — one hell of an enjoyable episode of Star Trek: The Next Generation.

Eighteen months later: Surgically altered to appear Cardassian, Nana Visitor wakes up on Cardassia Prime looking incredibly striking, but her rich backstory, the show’s increasingly involved premise, and her willingness to just go for it as an actor — all of these combine to make one hell of an enjoyable and satisfying episode of Star Trek: Deep Space Nine.
