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