How does Nebula escape?
Although she didn't have much screen time in the movie, Nebula still played an integral role to Infinity War's story. Part of that was because she inadvertently revealed that Gamora knew where the Soul Stone was and she's one of the few remaining people alive after the disintegration. While her story arc was straightforward, one thing is unclear, how does she escape the Sanctuary-II?
Nebula was being imprisoned on Thanos' ship, and she was able to kill the guard and escape without breaking a sweat. How? Sure, it was mentioned earlier that she came very close to assassinating Thanos, so she obviously knows her way around the ship, but how she managed to escape from the chamber she was being held in is still a mystery.
What was Thanos' dreamworld?
After defeating both the Avengers and the Guardians, and then snapping his fingers and wiping out half of all life in the universe, Thanos awakes in some sort of dreamworld. In it, he sees a young Gamora (probably because she's the person that he loves the most and he had to sacrifice her to get the Soul Stone), who asks him if he succeeded in his plan and what it cost him - everything.
While it's never revealed exactly where Thanos went, it's presumed that he traveled to the Soulworld. In the comics, the Soulworld is a place located within a pocket dimension that uses the Soul Stone to draw in people (or those who wield the Soul Stone). A number of people have visited the Soulworld in the comics, but Thanos might be the only person to do so in the movies, but that's still unclear.
What's Doctor Strange's "Endgame" plan?
What's Doctor Strange's endgame? He used the Time Stone to look into the future and saw millions of possible timelines unfold before his eyes. Out of all of them, there was only one in which the Avengers and Guardians succeed in their effort to stop Thanos - but that's not what happened. Rather than let Thanos kill Iron Man and then presumably everyone else, Doctor Strange willingly gave up the Time Stone, thus forsaking his sacred oath as Sorcerer Supreme (or the master of the mystic arts).
Thanos succeeded in wiping out half the universe by the end of the film, and it seems that Doctor Strange's plan didn't work. However, that may not be the case. Since Avengers 4 is right around the corner, it's possible that the future Strange saw was one in which they had to sacrifice themselves and let Thanos win initially, only to come back stronger in the second film... with Captain Marvel in tow. So, while we don't know what Doctor Strange's endgame is, it should be something that we find out come 2019.
How will Marvel TV shows handle Infinity War's ending?
It's strange to think that the Defenders and, at least, S.H.I.E.L.D. wouldn't try to come to the rescue when the Black Order's ship arrives in New York City, not to mention everywhere else the Children of Thanos go looking for the Infinity Stones. That was something that was repeatedly asked leading into Infinity War, and it's a question that won't go away anytime soon.
Sure, they all got their hands full, and S.H.I.E.L.D. is busy saving the world again, so audiences may not find out exactly how Infinity War affects Agents of S.H.I.E.L.D. until next season, aside from a handful of throwaway Infinity War references. But with half of the planet's population gone, it can't be easy for everyone to go about their days like everything is fine.
How does Fury know Captain Marvel doesn't disintegrate?
At the end of the film, half of all the heroes (and all life in the universe) is wiped out by Thanos snapping his fingers. It's a big cliffhanger and major setup for Avengers 4 in 2019, but a number of people aren't shown on screen, so it's unclear what their statuses are. First, Hawkeye (who isn't in the movie at all), Shuri, and Wong aren't seen on screen, which means they are probably alive. The same applies to Ant-Man, Wasp, and the rest of their supporting cast since they will all be seen in Ant-Man and The Wasp this summer.
Another person that isn't shown but hinted at in the movie, and who isn't confirmed to have disintegrated, is Captain Marvel. In Infinity War's post-credits scene, Nick Fury sends a message to Captain Marvel. And while the message is received, but why does Fury think to do that specifically? Plus, how does he know she hasn't disintegrated like everyone else? Sure, we know Captain Marvel is the final movie before Avengers 4 releases and that Brie Larson will appear in the final Avengers film as the iconic superhero. So, that's the meta reason, but what's the in-universe reason?
