[Shun's reasoning is more along the lines of his personal wariness around people he doesn't know, but as long as he's not having anyone he doesn't want inside his space, he doesn't care too much what their reason is.

Shun notes that he's been here a while - he's never met the guy before, but it wouldn't be the first time he'd missed people in that sense.] How long is "some time"?

[And that explanation of the ability makes a little more sense, and makes it sound a lot more like something grounded in where this guy came from and presumably something of what he is. Shun nods a little to indicate he gets it more now.] So similar to someone using magic, or even a borderline, though maybe not drawing on exactly the same thing.
