Cole remains quiet. If Pumpkin doesn't like him snapping or talking, then he will try his hardest not to snap or talk. Which...might be a bit hard, considering that Peridot is asking him a question. There's a brief pause before Cole nods. Then there's another brief pause before he continues with,

"I can hear the hurt. Even in Pumpkins."

And to his credit, Cole's a bit more quiet and tentative now.
