[Vin has approximately zero idea what she's doing - and it shows. The recording starts with her eyeball pressed up against the camera, and a voice, muffled by her face pressed against the microphone, insisting that this is not how it's done. Jerking back, she stares blankly at the screen for a few seconds, moving side to side, tracking her own appearance in the playback software. She turns to the side.]
Are you sure this is right?
[She is assured that, yes, this is right, and she ought to pay attention to what she's doing instead of talking to him. Scowling slightly at Henry, Vin turns back to the screen.]
Hello. [An awkward pause where a nice, normal greeting should go. Something like "it's nice to meet you." Vin is very bad at being people.] I was wondering if-- you're sure this is working? [A huff. She turns back.]
Is anyone here familiar with metallurgy? I can pay for your time. And provide materials.

[He's just sort of imagining her flicking them at people, and that doesn't seem nearly dramatic enough.]
Voice;
Then she realizes he probably has no idea what that means.]
I can burn all the metals. So I can burn iron and steel, Ironpulling and Steelpushing. All Mistborn use coins as weapons. And to move around.
Voice;
Ah, but what do you do when you use them as weapons? What does burning these metals do for you?
Voice;
Mistborn swallow bits of metal. When we burn iron and steel, we can push and pull on any metal. I can Push on a coin and send it flying. Or I can Pull on another coin. Pushing and Pulling is based on weight. When I burn iron or steel, it's one hundred pounds of force behind a bit of metal.
Voice;
I can see why you'd prefer that over weapons, in that case.
Voice;
Until you have to deal with Hazekillers or other Coinshots or Lurchers.
Voice;
There probably aren't many people here who can do what you do, so you're probably safe from whatever those people can do.

[Knowing how it would work could give him some insight on how people might try and disable her, after all.]
