She'll happily listen to and take notes on that. And follow him around to continue being close enough to hear.
That seems reasonable enough. He's known her less than a day.
"Put me by my car," she says. "I'll go home and be nice to my dad this month."
She has a script for why she disappeared from the hospital that will usually get her dad off her back. It doesn't work as well as usual - he has heard about the spaceship; it's got him on edge - but she says it wasn't there when she first drove by (true; she first drove by resets ago) and that on her way back it was already a police cordon (also true). She makes dinner. They eat. She goes to the library and gets some books she hasn't read and reads them all evening.
"Not yet. I found some of the precursors, but not every critical material. To use a metaphor, you can't make bronze without tin, and I'm missing the tin. I'll deliver you the scanner, but I need you to duplicate more deutritium cells, running my sublight engines this hot burns through fuel really fast."
"Sure. Can you find me by this communicator if I drive out someplace unobserved?"
"I won't take too long. Advantages to living in the middle of nowhere."
And the someone produces more deuterium and copies the witch scanner. "What this will be good for," she says, "is finding more puella magi. I know a few in the area, but if you can finagle me a vehicle I could find more of them and maybe pull off some kind of massive team-up."
"As far as my sensors can tell, witches are not a living thing. So the ray gun will have lots of very fancy computerized safeties that make it not capable of firing at any living thing larger than, like, a blade of grass, unless it's attacking you. Trying to remove the safeties will slag it. It takes the same power sources as the scanners, and the power dial goes from 1 to 8. One is 'stun,' two is 'singed,' and so on right up to eight which is 'burned to a crisp'."
"Do your sensors," Bella wonders, "think that I am definitely a living thing?"
"My mind no longer actually runs on my brain. My whole body is being operated from my soul gem. Part of being a puella magi."
