Ange glances up from what she was looking at - nothing too interesting, or it would have held her attention more to try and figure things out from what she's seeing - to shoot a straight look at Emet-Selch.

It's a look that lingers for a moment or two, like she's trying to figure something out here, but when she can't seem to tell from appearances, she just flat-out asks:

"Are you human?"

You know.

A totally normal question to ask someone else in the middle of all of this, right. Nothing strange going on here.
