Star Trek: Discovery 3.10 Review: Ups And Downs From Terra Firma, Part 2

In the Mirror Universe, Georgiou is Emperor and Saru is her slave. However, in both last week's episode and this week's, there is a deeper relationship between the two - one that develops quickly, thanks to Georgiou's position of power and the kindness that she shows to him.

While he is terrified that he is about to undergo his change and be culled, Georgiou gives him information that could potentially be devastating for the Terran Empire - she tells him that the subjugation of his people was based entirely on a lie.

When the shock of this passes, he correctly identifies that she is not a Terran. At least, it would be more accurate to say that she is not a Terran anymore, as it has become clear from both last week and this week that she has been irrevocably changed by her experiences in the Prime Universe.

There is an understanding between the two - one that will pay off as the episode continues.
