You are Cas's adopted child. You are at a diner with him, eating burgers and fries. Sam, Dean, and Jack are on a case.

After Cas rants to you about his favorite bugs, because he's just silly like that, you start talking about your favorite movies. He's listening while sipping lemonade.

"So... who's your favorite character?" he asks, confused. Apparently you like too many characters from your favorite movie. He wants you to choose one... such an impossible task.
