They're under a ruined overpass when he spots it, next to a quietly burbling stream.
"Hey, 2B, look at that."
Tomorrow. But they need us here, you heard them. We can do more to help humans here than we ever could smashing the inexhaustible scrap back home.
She has more questions and wants to know more of all sorts but they can talk on the road; she can't experiment as well on the road. So she experiments.
Doesn't understand the 'internal combustion' thing well enough to try it yet ('make a lot of fire' isn't a new idea and has not been seen to cause anyone to move anywhere), doesn't understand the 'laser' thing well enough yet, so, about these 'atoms'.
She has some gold and silver she'd brought along, iron's around, obviously. Poke, poke, poke, and trying some other things in between.
She doesn't get much of anywhere before she really ought to go sleep herself, but that's rather something in itself - to have something to really work on. (Fascinating is understating things).
(She keeps aware of the androids (maybe with some dropping of such when she gets very engrossed, but it's probably fine...), leaves up extra wards. Doesn't interfere with them otherwise.)
She ends up waking up before Genea too.
Does a bit more attempted-experimenting, sitting next to her.
"Morning, fore-citizen," she says once Genea's awake. This is fascinating. Almost makes me not want to go and play a mage-slave. Don't worry, I'll still do it. And I can think when I'm at work and experiment when I sneak out at night.
Well then they can do that on about the same routine (teleportation and walking, breaks, stops for the night) until they get to where they're going.
