Ezra: "Aren't you guys done yet?"
Ethan and Taylor: "We're getting there."
Ezra (He frowns. He's clearly miffed.): "I'll be back in 20 minutes," he said, wagging his finger at them. "It better be done."
And with that he marched back downstairs. I think his brothers got the message. After they started laughing and wondering who put Ezra in charge.
