Man, that makes him nostalgic. "My dad was a marine biologist. My mom, she was the hero in the family. A nurse." Really, they were both heroes. It's a discussion he heard them having over and over while he grew up, although he doesn't need to share that with Dinah or with anyone. They're gone and the memories -- like the one of that playful argument -- that's all he has of them.

That's all he has of most things.

"What was he like? Your dad, I mean."
