[he's not sure if they're joking about the god part until John says it and it shows on his face, a mix of interest and uncertainty as each one of them speaks like it's a given fact that they're gods. it's harder to tell when he can't sense anything; the nearest rock could be a seraphim and he wouldn't be able to tell at the moment.]

They don't have wings normally. I definitely would have noticed if they had wings. It could be that seraphim are something different where you're all from. Or they just look different.

[although he wouldn't be surprised if all of them turned out to be seraphim instead of gods]

I can see them because I grew up with them; supposedly I developed the ability at a young age, but I've been able to see them for as long as I can remember. I'm just a normal human though.
