While grappling with the fallout of her recent actions, and what her future might hold, Burnham agrees to represent the Federation in an intense debate about the release of politically sensitive – but highly valuable – Burn data.

Without wishing to sound like a stuck record, Star Trek for me is less about the space battles than the human adventures with other races. And while Kirsten Beyer’s excellent episode of Discovery this week is a ‘bottle show’ to a large extent, it hits home in a particularly emotional way that no other episode has this year.

With references to the unification of the Vulcan and Romulan empires, footage of Leonard Nimoy, and even the inclusion of recent additions the Qowat Milat warrior nuns from Star Trek: Picard, it’s an hour that uses its heritage wisely. It’s good to see The Burn being at the forefront of the plot, and there’s certainly traction now around Michael’s investigation of its source.

Mary Wiseman continues to steal every scene she’s in as Tilly, and the response from her colleagues to her proposed promotion is beautiful. There’s no Adira, Grey or Philippa this week, but there’s at least one surprise moment to catch you out.

Verdict: A really strong episode that plays to Star Trek’s strengths while also pushing this season’s central McGuffin forwards at this halfway point in the run. 9/10
