Donald
- Donald: When I was a kid, it seemed like they made something new every day. Some, gadget or idea, like every day was Christmas. But six billion people, just imagine that. And every last one of them trying to have it all. This world isn't so bad. You're the one who doesn't belong. Born forty years too late, or forty years too early... My daughter knew it, God bless her. And your kids know it. Especially Murph.
- Donald: [looking in at Cooper and Murph, who are staring at the dust anomaly on the floor] You wanna clean that up... when you're finished praying to it?
