She takes his hand. "What're you worried about?" 

"Forgetting my mom."

"It won't be that bad, I promise. I still remember my parents."

"Oh. Okay, then."

"Of course, first we have to determine if you even have the virus."

"If I don't you can just inject me."

She gives him an odd look.

"Hm?"

"I'm just not sure whether or not that would be a good idea."

"Why?"

"You're something of an anomaly. I don't know how the virus might interact with you."

"...you're letting me interact with your kids and you and your friend."

"That was an oversight on my part. I suppose the damage is done."

"Okay but why can't you inject me anyway?"

"I can, and I probably will. It's just when I came up, Huxley's flu was a plague. It depopulated whole villages of children."

"...oh."

"I may know in my mind that you'd have nothing to fear, but it still makes me anxious. And it would make a lot of people much more than anxious, if the AA started doing it on a large scale."

"But that's silly."

"It is, Sadde, it is. But it's also powerfully silly. You know, you should speak to Maurice about this later. Or maybe Paul."

"Okay."

"Just remember, for all you know, baby obsession is a side effect."

"Maurice doesn't have it," he points out.

She just laughs and laughs and laughs.

"...what?"

"Hannah has blueprints drawn up."
