What were the reasons behind putting Aeryn in a coolant suit in Promises?
That came to me along the way, because it felt like since she's going to keep closemouthed about what she's got into, and what she's doing with Scorpius, John's going to be wondering, as the audience will be.
In Farscape fashion, we want to see some of those worries. Instead of [John] just saying to D'Argo, "I'm worried that he put a thing in her head," let's see that, let's show some of the nightmare scenarios. Then it hit me. If putting a chip in Crichton's head turned him into Crichton/Scorpius, if he fears that something similar is happening to Aeryn, she's been brainwashed or chipped by Scorpius, then let's put Claudey in the make-up as well. Give her a chance to see what fun hot flesh [the particular make-up technique] is.
It was a thing which almost didn't make it into the episode, because it became such a production problem. There's so much in each episode that it's tough to squeeze it into ten days, and to take Claudia and, for a two page scene, to have her spend three hours in make-up just became very tough to schedule.
But the director fought for it, and said, "No, we're going to do it even if we have to go back and pick it up on some other day. You can't go through an episode like that and not use that great visual." And, by god, we got it.
