I read elsewhere that the Grayza-Braca scene added to the "Previously on" was shot for "Crichton Kicks", but then cut for time and because it was thought that the episode worked better if the action was solely confined to Elack.

Grayza - in my posts when I first watched the show, and I still think so, it's a rare example of one of Farscape's usual positives working against it. Because otherwise the show has a sterling record of taking sexualised concepts that are used in other shows for juvenile jokes and/or fanservice, and taking them seriously in a genuinely adult (as in mature) way. However, the writers here seem to be working on the assumption or false memory that Blake's 7 depicted Servalan as a shallow bimbo who slept her way to the top, which is a really gross (in every sense of the word) misreading of the original show and the character (obviously they decided to rewatch a couple of B7 episodes and picked Ben Steed ones). Sort of a gender-flipped villainous, and more misogynistic, version of the "Kirk was a lust-driven horndog who seduced every hot alien babe who crossed his path" false memory of Star Trek TOS
