Harley wasn't like that one cold, cold girl, who - she wasn't even technically a sociopath. Sociopaths kindle like everyone else. She was just - cold. Like an airless environment in which no fire can burn.
But Aelise had her killed, and Chelsa made sure no one would miss her, and if anything like that ever happened again, Chelsa has every confidence that Aelise would make it right. Harley's one thing. He can just be - out of sight, out of mind. Aelise would never expect Chelsa to compromise on the existence of such a terrible cold.
"You'd have to lie," Aelise reminds her. "But yes, I could find a disease like that, and a doctor to lie and say you have it. As for making them immortal... right now, I can only make very few people immortal. I'm going to try something soon that might let me make everyone immortal. If it works, your parents will be part of everyone. If it doesn't, I might have room for them, or I might not. But your parents aren't very old right now, so there's plenty of time to figure that out."
"No," says Aelise. "I can't make people that kind of immortal. I can only make them younger, down to about eighteen or twenty, and a little bit healthier, so they don't die of old age and usually don't get sick."
"It's what I've got. If I found a way to make everyone properly immortal, that would solve a lot of problems. And I don't think I'd use it on Chelsa."
"Not a lot of people do," says Aelise. "I think she's plenty nice. My mother died when I was a little younger than you are, and Kers raised me from there."
"That's a secret. It's such a big secret, I can't tell you until I take you there, even though you're a pretty big secret yourself."
The doctor collects Mehitabel eventually, and then Aelise puts the doctor back where she found him.
