[while Mr. Rubadoux walks away after the funeral ceremony of Mrs. Rubadoux he sees Carter
Mr. Rubadoux. I'm very sorry about your wife. I made a mistake. Not in the way I treated her, but in the way I treated you. I wasn't honest, wasn't fair. I was wrong. And I am very, very sorry.
Jules 'Ruby' Rubadoux
This day isn't about you, Mr. Carter.
