Well. Actually, that's kind of concerning. The pinch is unwanted, but Lapis watches with a mix of abject horror and fascination as the hypospray fills with blue.

She inspects her arm after it's taken away, trying to figure out just what the heck happened there. Also, importantly, she points at the vial, unmoving from her spot. "What's that?" Because while Lapis vaguely understands the concept of blood (Thanks, daytime TV), she doesn't understand what that is. It's not blood. It can't be. She doesn't have blood unless she shape shifts. And she never shape shifts.
