Warning: this post contains major spoilers so if you didn't watch Avengers: Infinity War then you should probably go and do that or at least check out a recap before you hate me forever. Or if this is how you absorb movies instead of watching, then just keep on reading this breakdown.
Marvel just dropped the trailer for Avengers: Endgame, which is the direct sequel to Infinity War. And it starts off pretty bleak, featuring Tony Stark wandering through space without food or water, leaving a message to the love of his life, Pepper Potts, a few hours before he runs out of oxygen for good.
Ugh, I know, sadness layered on sadness is kinda gauche. Especially after the events of Infinity War and seeing all of your favorite heroes disappear and turn to dust before your very eyes, it's easy to sit around and wonder just what the heck our gang of super people are going to do to reverse what Thanos has done.

But if you've ever read the Infinity War comics, then you know exactly what you're in store for: a raging comeback from the heroes, courtesy of the Infinity Gauntlet and an unlikely team-up with Thanos to defeat Nebula after she gets a hold of the uber-powerful glove capable of altering the very fabric of reality.
But like anyone who's ever followed a book-to-film adaptation will tell you, the movies aren't always like the source material. And the Avengers series is no different. After watching the trailer for Avengers: Endgame, here's what we know:
Who survived the snap that's featured in the trailer?

The characters we know survived the snap are Steve Rogers, Tony Stark, Thor, Natasha Romanoff, War Machine, Rocket Raccoon, Nebula, Okoye, and M'Baku — and Ant-Man, but his fate is a bit complicated.
But not all of these heroes are featured in the trailer: Iron Man, Thanos (living on his farm on some distant planet, using his armor as a scarecrow), Captain America, Thor, Black Widow, Bruce Banner, Nebula, Hawkeye (who came as a surprise) and another character at the end of the trailer who was probably the biggest surprise: Ant-Man. All of them will play prominent roles in the fight to undo the work Thanos has done or at least bring that big purple dork to justice.
Why is Ant-Man's survival so significant?

Viewers of Ant-Man and the Wasp who stayed to watch the film's ending credits will know that Scott Lang went sub-atomic with Dr. Hank Pym, Hope, and Janet Van Dyne supervising his transition into the unknown from regular-sized land.
If you've watched the Ant-Man movies then you know that going sub-atomic is scary, because you're essentially entering another reality so microscopic and tiny that there's no going back, unless you've got a whole team of people busting their humps to do so, as proven at the end of Ant-Man and the Wasp when Hope's mother, Janet, was brought back to the regular-sized world.

While Scott's in the subatomic realm, Thanos' "snap" decimation happened, and sadly Pym, Janet, and Hope were all random victims of the universal 50/50 genocide. The scene is a sobering one, leaving viewers to believe that Ant-Man was going to be out of the next Infinity War film because there's no way he'd be able to bring himself back from the realm.
But the fact that he was able to return from the Quantum Realm and ask the Avengers for help in the latest trailer, has got people very, very interested. In fact, it's probably the key to how the Avengers are going to reverse the events of Infinity War.

When Janet returned from the Quantum Realm, she was able to heal the film's primary villain, Ghost, with newfound powers she obtained while living in the sub-atomic space. This might be the key to bringing certain characters back from the dead, or, it may have a tie-in to a plot device from the Infinity War comics.
And that's messing with the very fabric of reality and time. Thanos was able to use it with the Infinity Gauntlet, and at the end of Avengers: Infinity War, it's pretty evident after Thor drives Stormbreaker into Thanos' chest and the Mad Titan manages to pull off the snap, that the golden glove isn't the same anymore.

In fact, the Russo brothers confirmed that not only was the Infinity Gauntlet destroyed after the snap, but that the act took a little something out of Thanos, himself — which means that he might not be as difficult to defeat in the second film.
In the Infinity War comics, the Infinity Gauntlet is used to reverse the events after Thanos' snap in an attempt to defeat Nebula after she gains control of the Gauntlet. But with the glove broken, it could be that the Russo brothers are having our heroes work with only a partially working super-weapon.

So, there's a huge chance that the reversal of those events can still happen, but it has less to do with our heroes gaining control of the Infinity Gauntlet, and more to do with Scott Lang's return from the Quantum Realm. I mean why else would you dramatically push that last bit of information to the end of the trailer everyone's been waiting to see?
Who didn't survive the snap?

In case you don't remember, or you're suffering from post-traumatic stress and have pushed the events out of your mind, there were a lot of heroes who didn't manage to make it out of Thanos' snap alive.
Black Panther, Spiderman, Doctor Strange, Winter Soldier, Scarlet Witch, Star Lord, Drax, Mantis, Nick Fury, Maria Hill, Hope, Hank, and Janet all perished during Thanos' snap. So, if the roles are reversed, then that means there's a good chance they'll be brought back.

But there are other characters who died before Thanos even snapped his fingers, and it'll be interesting to see if the Russo brothers bring them back. Namely Loki, Heimdall, Gamora, and Vision.
With Loki, you can never be really sure he's been killed: the dude's the sneakiest of the sneaky. As for Vision, he's technically a robot, so stealing the reality stone from his head might've "killed" him, but it really just killed his personality. Plus, in the comics after that stone was torn from his head he came back as Colorblind Vision. Basically, Vision, but without a soul.

I just hope that if everyone is brought back, someone gives Star Lord a big slap in the face for letting his emotions get in the way of saving the galaxy. What a nerd move.
