"No, no..." At least Vincent's awkward stab at conversation is met with wholehearted agreement. He might accidentally be speaking right at Phalanx's level. "They don't. We don't."

And, goodness Phalanx sounds pretty close now. By the best guess, they must be propped up on their knees and peering right at Vincent's face, and it's followed by a pause that sounds an awful lot like staring. And a second or two after that comes a little gasp of surprise.

"...Glass!"

Vincent can't see it, but there's a finger pointed alarmingly close to his face.
