Now that you've seen the ending/epilogue to the "Justice League" Snyder Cut, let's get down to what happened. Yes, the four-hour epic ended with a crazy moment that left fans either screaming for more or yelling "WTF?"

Of course, what follows is a massive spoiler, so either you've already seen the Snyder Cut or accept that you don't have those four hours in a day or a week.

With that out of the way, let me explain what the epilogue to Snyder Cut, or the true ending of the film, is.

First, let's skip over the Lex Luthor (Jesse Eisenberg) scene, since we've already covered that in 2017's Justice League. Lex escapes Arkham and Deathstroke (Joe Manganiello) comes to talk to the supervillain on his yacht; the two talk about forming an antithesis to the Justice League (possibly the Legion of Doom), and Lex's secret identity as Batman's Bruce Wayne is revealed.

Then we jump cut to a completely different version of the DC universe. [It begins in a Mad Max-like desert dystopia. Darkseid parademons are flying all over the place and giant ships are setting big cities on fire. Then Batman, armed with a giant gun, emerges from behind a car. This is the reality foretold in Batman vs. Superman: Rise of Justice.

Cyborg, Queen Mera, Flash, and (gasp) Deathstroke are allied with Bruce on some mission. Yes, Slade Wilson has somehow managed to make good on his grudge against Batman - so much so that Darkseid has created the worst situation for the citizens of Earth.

After Mera becomes furious about who hurt (or likely killed) Arthur (who is Aquaman), infighting breaks out among the heroes. Mera does not believe that Batman can understand her feelings and asks if the caped crusader has ever loved anyone. Then comes the moment that some fans have been waiting for since the last trailer.

With a familiar laugh from off camera, we learn that the Joker (Jared Leto's version) is also a member of this caravan of hobos. And this clown prince of the crime world lays out the names of dead loved ones from Bruce Wayne's past. The two become acrimonious, and the Joker pesters Batman about his past.

It is revealed that Robin's death happened the same way Harley Quinn's death happened. The Joker insists that Batman needs him to stop the dark side.

But before they can throw down, and after the Joker says that Batman "let" Lois Lane die, we discover that all is not right within the Justice League. Cyborg realizes they have been discovered and the caped being crashes to the ground. Superman is angry. The Joker laughs again, Kal-El's eyes turn red, and ....... Bruce wakes up.

Yes, he had been seeing the terrifying apparition commonly known as the Nightmare (Dark Knight + Nightmare). In this world, Superman reigns supreme and Batman is in revolt. The term nightmare is not exactly a canonical name--although Snyder himself uses the term.

Bruce Wayne wakes up from this nightmare - or was it a vision of his future? Either way, let's rewind to the beginning of the film where the Justice League had some help in resurrecting Superman.

The Martha Kent who convinced Lois Lane to live her life over again was not actually Martha. As her eyes glowed red, she transformed into another being, then into Secretary of Defense Calvin Swanwick (Harry Lennix), who has been part of the DCEU since Man of Steel. Then he left, and many exclaimed that the fan theory was true: Swanwick was the galactic good guy, Martian Manhunter.

Now the being returns to speak with Bruce Wayne, reminding him that the Darkseid threat is not over. This conversation is not necessarily about Nightmare, but it certainly feels relevant. It means that if Darkseid does not find the anti-life equation he desires, nothing but doom awaits him.

In a production note released to the press by Warner Media, Snyder admits that this epilogue does not close doors, but rather creates opportunities. 'It opens a door. The key concept is that the Joker killed Robin. What this scene reveals is that Harley died and Batman was there at that moment. And that the Joker has to fix the world for Batman, part of the post-apocalyptic nightmarish reality that we were aiming for in the second and third films."

These endings definitely set up a sequel. The bad news, however, is that there are no plans for a follow-up to "Snyder Cut. In an interview with Beyond the Trailer, Snyder himself called the film a stand-alone of sorts; it is not a canonical DCEU film, and Snyder has said that "Snyder Cut" happens in a sort of Elseworlds continuity.

In other words, don't expect these events to continue with upcoming DC films like "Batman," "The Flash," and "Aquaman 2." When asked about sequels, Deborah Snyder told Inverse, "Right now, Warner Bros. and DC are going in different directions with movies in development."

Nevertheless, if "Snyder Cut" proves to be a success inside Warner Bros. Pictures, I would not be surprised to hear of a sequel. The Snyderverse could stand alongside the DCEU film series, which would not be entirely impossible. Yes, it's confusing, but there is no future where studios won't consider a profitable blockbuster because it's "weird."

In particular, Snyder seems to know exactly what his Justice League is about. When asked (in production notes) about "Martian Man," he said, "Traditionally, in the genre, the coda leads us to the next film or the next universe. For years, I had been thinking about making Swanwick's alter ego the Martian Manhunter. I really saw him as a stepping stone. And finally, I'm bringing him back to start a war on the dark side." Ominous words.
