Kind of reminds me of the ending to Season 3 of Fargo that just finished (SPOILER ALERT!).
5 years after the story ends, the humble female cop now works for DHS, and is interrogating the evil mastermind in Brussels. She tells him, “in five minutes three men will come through that door, put you on a plane to NYC and take you to Rikers Island where you will be charged with 1st degree murder and income tax evasion, and I’ll go home and take my son to the State Fair for fried Snickers”.
He says “I’ll tell you what will happen, in less than five minutes a man who you will be powerless to stop will walk through that door with an order for me to be released”.
She thinks for a second, then says, “Nope, Rikers and Snickers”. He just smiles at her and the camera shows the door and fades out. The viewer is left to decide how it ends, and by extension what kind of world we really live in.
That’s a pretty good “The Lady or the Tiger”-type of ending.
