Robert sits on the opposite end of the bench after Sarah invites him.

He gently gestures toward his prosthetic leg.

ROBERT: "I lost this leg a long time ago."

Lily stares at it.

LILY: "Does that mean you're not a grandpa anymore?"

Robert smiles.

ROBERT: "What do you think?"

Lily thinks carefully.

LILY: "No. You're still a grandpa."

ROBERT: "Exactly."

He takes a small photograph from his wallet.

It shows a smiling young girl sitting beside him.

ROBERT: "My granddaughter once asked me why my leg looked different. I told her I had been badly hurt, but I was still the same Grandpa who loved her."

Lily looks back at Jack.

LILY: "But he used to have two arms."

ROBERT: "That's true. And it's okay to feel surprised or upset about that."

Robert pauses.

ROBERT: "But losing part of your body doesn't erase the people you love."

Lily doesn't answer.

Robert reaches into his jacket pocket and produces a tiny paper airplane.

ROBERT: "My granddaughter made this for me. She says I may not run as fast as before, but I can still help her fly things."

He sends the airplane gliding gently across the floor toward Jack.

Jack catches it with his left hand.

For the first time, Lily almost smiles.

Jack notices.

He picks up the paper airplane and folds its wings back into shape.

JACK: "I used to make these when I was little."

LILY: "My daddy makes airplanes."

Jack looks up.

JACK: "He does?"

LILY: "Mommy showed me a video."

Jack laughs softly.

JACK: "Then maybe he's still pretty good at it."

But Lily remains uncertain.

She turns to Robert.

LILY: "What if I want my old daddy back?"

Robert doesn't rush to answer.

ROBERT: "You can miss how things used to be and still get to know who he is now."

Lily looks down at the little airplane.

For the first time, she doesn't move away when Jack sits a little closer.

CHAPTER END HOOK: Jack turns the airplane over.

On its wing, he writes two words that make Lily gasp.

"Sky Captain."
