Question, though: Aeryn saying Peacekeepers wouldn't dissect their prisoners in labs. Is this Aeryn still deluding herself, or are we supposed to believe our soon to be introduced main antagonist picked up the habit solely from the Scarran side of his heritage?

I think she's still a little reluctant to totally throw away everything she grew up with. "At least we wouldn't do THIS" isn't a great thing to hold on to, but it's not nothing.
