Born with it...[He frowns as he considers how normal she's being about this and what it must have been like to be invisible for her whole life. She'd never be able to check her reflection in a mirror or see what she looked like...how tragic! Or maybe she can see herself? He has no idea how it works. At any rate, no one else would be able to appreciate her if she wanted other people to look and that is definitely tragic!]

Abilities? [He shakes his head.] Well, some people have spiritual powers that they've trained, but no one is just born with something like that. And some heavenly officials and ghosts can turn invisible at times, at least to the human eye, but they always turns visible again, and anyway their clothes would be invisible too!

[Speaking of clothes, he takes in the clothing that she's wearing and can't help but marvel at it a little. It's very different from anything he's ever seen. It's dangerously short and form fitting. (He kind of wishes he could try something like it on. Just to see what it would look like.)]
