The Usual Suspects/WMG

In the 70s, Keyser Soze decided to fund a comedy troupe using the alias "Monty Python"
He needed a break from endless killing, and decided that the world needed a few more laughs, so he decided to front a few talented British comedians. Unfortunately, he couldn't shake his penchant for cloak and dagger tactics, and was only comfortable acting as a faceless Man Behind the Man. Hence, not even the comedians themselves have any idea who the hell "Monty Python" really is (or if he even exists), yet he continues to influence the world of comedy to this day. He has become an elusive, mythic figure whose name is synonymous with "surreal, eccentric humor". In short, he is the Keyser Soze of comedy.

Verbal Kint confessed to the murder of Dean Keaton during the interrogation
Towards the end of the movie, Kujan accuses "Verbal" of lying about the death of Dean Keaton. Kujan claims that Verbal couldn't possibly have actually witnessed Keaton's death, and given that Keaton had faked his death before, he could still be alive. Kujan's screaming leads Verbal Kint to yell out, briefly, "I did, I did kill Keaton." Before quickly correcting himself. Kujan doesn't notice because he's so convinced that Keaton's guilty, he didn't hear that Verbal literally said, "I killed Dean Keaton"


 * I like that theory-I kind of thought something similar was possible-

The twist ending is partially conscious of one twist ending from The Twilight Zone
(To give credit where credit is due, this WMG came from my Film Arts professor). In, a man --in The Reveal, where , the man realizes what just happened but is powerless to undo the mistake. Considering that Soze is consistently compared to the Devil, and Kobayashi's demeanor when you see him driving the getaway car is nearly demonic, it is possible that there is a very subtle Shout-Out gong on here. But it may just be coincidence; there are enough dissimilarities for it.

If nothing else, the music is kind of similar. Observe the ending montage in The Usual Suspects and the ending montage in the episode in question.

Keyser Soze is the Greek's son
Consider their near identical business operations and practises. Both ar concerned with drugs, people trafficing and murder. They both remain behind the scenes having others as thir spokesmen. Now consider Soze's possibly German father and the fact that the Greek says he is not really Greek. The story Verbal tells Kujan about Soze in Turkey is actually the story of the Greek before he came to America, where he had a son who would be a naturalised U.S. citizen. They both use the legend to create a mythical supernatural status, He-Who-Shall-Not-Be-Fucked-With.

Other than Verbal Kint told Kujan the real story.
Verbal tells the truth to Kujan, knowing already that Kujan's obsession with Keaton would blind Kujan from the truth. And allow Verbal to walk away...

Keaton knew .
Keaton was the only one among the other criminals who knew Kint and could vouch for him. Keaton's background as a crooked cop who kept having all these lucky breaks happen his way suggested

It was never about killing the 'one person who could identify Söze'.
Just Bugs Me seems to have established that if the entire set-up (assuming, aside from the obvious details, that Verbal is more or less telling the truth about what happened) was really about getting rid of the single person who could identify Keyser Söze, the events at the very end of the film basically render everything a rather bad loss for Söze. But think about it realistically for a moment and you realise that there's almost no way this man can be that elusive; and even if he is, what actual threat is the mere ability to identify a face with an urban legend? Without solid evidence of crimes, Söze's as scott-free as ever whether someone outside his organisation can put a face to his name or not. So it's very unlikely that whatever the Suspects were brought upon that ship to do, it was to provide a cover for Söze to kill the supposed sole person who can identify him. It may well have been to let him kill the Hungarian, but whatever reason he had to want to do that so badly most likely wasn't that he could identify him.

The ship job was Söze's final act of revenge, and last criminal act before retirement.
Related to the previous entry. In Verbal's story, Soze gets revenge on the other mob bosses by killing off their families, their contacts, etc. The Hungarian on the ship was the final person he needed to kill to complete his revenge. As his revenge is complete, he retires with his ill-gotten gains to some remote place and is never active again, "And like that, he's gone."

It seems pretty obvious on further reflection: why throw around a name like Keyser Soze if you have the means and skills to essentially change from one skill to another? is not actually known as Keyser Söze, he's probably not even Turkish - it's a story made up, who also is a made up character. In the end, the police have two names the have no use for. After all, a name like Keyser Soze (which to a German speaker still sounds like Kaiser Sauce) is likely to be fake. Sure, Soze exists as a carefully placed myth, but remains as such. disappears, and without probable cause, his mugshot will soon be forgotten. and possible the Soze persona have both served their purpose and will be shed like an old skin - or as Kint put it "And then ... you'll probably never hear of him again."
