DIANE: Jake, do you go to the doctor's a lot now?

JAKE: Uh huh.

DIANE: What do they do at the doctor's?

JAKE: Take my heart.

DIANE: Take pictures of your heart -- what's that called?

JAKE: Take a picture of my heart.

DIANE: Matthew (Jake's brother), when they take pictures of Jake's heart, what's it called? What's it called? I know you know. We go for what? X-rays. You know that. What's an x-ray show you?

MATTHEW: It shows you Jake's bones.

DIANE: Bones, and his heart and his lungs -- everything inside, underneath your skin, right? It's a special camera.

DIANE: What do you have to do when they take your picture?

JAKE: My heart.

DIANE: Of your heart -- what do you have to do?

JAKE: Behave.

DIANE: Behave? Can you move around?

JAKE: No.

DIANE: What do you have to do?

JAKE: Take picture of my heart.

DIANE: You have to stay very still, right?

JAKE: Right.
