"That's a uterine replicator."

"...oh, that's really good, also kind of a big problem - I should write my peal about it -" Note for them! In one of the Hex idiolects, just in case there are other demons conjuring Cam's mail.

"Why's it a problem?"

"Demons can't make people but I bet we can make those. And make those with five-week-old embryos in them."

"And doing that with mindless person-copies wouldn't have worked?" guesses Cordelia.

"Yeah, they don't carry the baby to term. Dunno why."

"Interesting. Well. Nika, would you like to find out more about where you came from and what proportion of your ancestors are magical?"

"Yeah."

Grandparents? Great grandparents?

He can get one grandparent, three great ones...

He shows this to everyone. "So it's not that everybody's magic, but it looks like if you have a magic parent you're magic. So far, at least - small sample -"

"I wonder why I got doorstepped."

"I can freeze-frame it but that doesn't do much when you can't get the actual people -" with Maiar you don't get anything if you're going for them but you can get their body when they have one, can he get a plastic Nika-body that way -

Yes actually!

"Okay so it might be that if I'm aiming a bit differently I can freeze-frame normally -" Trying like that, was anyone in the room when she was born -

Yup, there's a doctor-looking person.

...complete written works of that person pull anything up?

Yup, here's some stuff.

"Spy on that guy or keep freezeframing-"

"Hmm... keep freezeframing; I think I want to find out who removed her from that building and spy on them."

Scale model of the area and the bodies currently occupied by the magical people, thirty second increments -

The doctor decants baby Nika and does various medical things and swaddles her up and gives her to some woman who carries her off and she spends four days in a perfectly ordinary house and then someone else comes and gets her and puts her on a ship -

"That the person we want to spy on?"

"Yes, let's try them."

Person accompanies her on the ship and travels to Barrayar and gives her to that pregnant lady where Uncle Simon's trail went cold and leaves.
