[There is perhaps just a slight hesitation here. But isn't not a secret. It would be weirder if it was. He isn't the only passenger here with someone in their head. It's fine. Friday will understand.]

There's a bit of my mother in my mind. She came with me, when I was brought here. Valdis met her when the memory cracks happened, and then I did too. Now my last gift from Sundries lets her write to me with the right pen and paper.

[He turns the book so Friday can read it. There, in a hand that is clearly not Siffleur's, teal-coloured letters work through various scenarios - how to maximize suffering without burning people out, how to maximize the suffering of a single person, how to generate suffering on a rotational basis, physical suffering vs emotional suffering, in-group/out-group dynamics for maximal social suffering, and so on and so on. This is something that has clearly been consuming the woman in Siffleur's head and so when he's set a pen to paper, it inevitably turns into her trying to solve a problem she's missing multiple variable for.]

She doesn't want out. Mother's finally happy and safe in my mind. But she worries a lot about the power, because it means we'll probably all die. I'm okay with that. I've had a really nice time here, and I like it a lot, but everything ends eventually.
