The Tourist/Heartwarming

"Elsie: You shouldn't be here!
 * Frank shows up at the ball, right after Elsie has firmly instructed him to go back to America before he gets killed.

Frank: No, Elise. This is the one place on earth I should be.

Elsie: How did you get in here?

Frank: I told the doorman you were my wife and I wanted to keep an eye on you. Italians are big on that kind of thing.

Elsie: (pleading) Leave!

Frank: No."
