The following contains MAJOR SPOILERS for Ant-Man and the Wasp. Come check it out after you've seen the film.
We knew that Ant-Man and the Wasp wasn't going to dwell too much on the larger Marvel Cinematic Universe story currently going on, but that doesn't mean it hasn't left us with its own big questions we need answered. The last Marvel movie of the year has set up the finale of the current phase of the MCU to get going next year, and while Avengers: Infinity War left us with far more questions than answers, the newest movie has just piled on top of that with more questions.
We now know what Ant-Man and the Wasp were doing during the events of Avengers: Infinity War, but we have even less idea what's going to happen next. Here are the biggest questions we have after seeing Ant-Man and the Wasp.
The last time we actually see Ghost in the film, she's on the run. She's been at least somewhat healed by Janet Van Dyne (Michelle Pfeiffer), but she has come to come to terms with what she did in order to try and get better and she clearly understands she's done some bad things. However, in the post-credits scene to Ant-Man and the Wasp, we see our heroes trying to obtain more healing particles from the Quantum Realm in order to help her. This tells us that Ghost (Hannah John-Kamen) will need more help before she is truly healed. It also implies that they know she needs the help, and that they think they can get these particles to her. Is Ghost on the run, or is she working with this team now?
After spending decades inside the Quantum Realm, Janet Van Dyne has absorbed a great deal of energy. She's able to simply infuse Ghost with some of it, which has at least begun the healing process -- even if it hasn't fixed her entirely. She clearly understood that she had the power, so she seems to know what it is... and what it can do. But we're clueless. Is she still human? Is she some other form of life now? How will this power affect the Marvel Cinematic Universe in the future?
The biggest moment of Ant-Man and the Wasp happens after the credits role as the instant we knew was coming finally happens. Hank Pym, Hope Van Dyne, and Janet Van Dyne all disintegrate into dust, victims of the Infinity Stones used by Thanos at the end of Avengers: Infinity War. While we know that Scott Lang survived, the status of everybody else is left up in the air. Is Ghost actually still alive? What about Luis? Scott Lang also has a daughter who is the most adorable thing in the world and the fact that she might be gone is sickening. Most of these characters are unlikely to have a major impact on Avengers 4, but somebody like Laurence Fishburn's Bill Foster still being alive, if he is, could be important with Hank Pym gone.
One of the ongoing gimmicks that Ant-Man and the Wasp uses to make things a bit more interesting the second time around is that the suit that Scott Lang is given is an experimental prototype Ant-Man suit which, as it turns out, still has some bugs to work out. Scott Lang grows and shrinks randomly and without warning at several points in the film. We're never told if the suit is entirely fixed. This could end up being quite important going forward. If Ant-Man ends up fighting alongside our other heroes in Avengers 4 it could be an issue if his suit continues to cause problems. On the other hand, if the suit accidentally increases his size to an extreme degree, maybe that will be what saves him from the Quantum Realm.
This may be a fairly small question in the grand scheme of things, but it's still one that desperately needs an answer. Randall Park's Agent Woo was the single best new addition to the MCU in Ant-Man and the Wasp. He needs to become a part of not only future Ant-Man films but the MCU as a whole. He can be the new Agent Coulson, showing up as needed as the all-purpose government agent that shows up whenever any Marvel movie needs one.
It's difficult to line up the chronology of Avengers: Infinity War and Ant-Man and the Wasp perfectly. There are a few places in both films where significant time could have passed between scenes. However, the one moment we can line up exactly is "the snap." This means the Battle of Wakanda is happening at the same time that Ant-Man is getting ready to enter the Quantum Realm. Which in turn means all the events of New York have already happened. Even if Scott doesn't know what's happening in Wakanda, wouldn't the guy who came to Captain America's aid in Civil War try to reach out and see what the Avengers are doing following the disappearance of Tony Stark, which we know made global headlines? Scott is no longer under house arrest at this point, so he's free to help.
And this, of course, brings us to the biggest question of all for Ant-Man and the Wasp. What the hell is going to happen to Scott Lang? He's apparently stuck in the Quantum Realm with no way out since the people who were supposed to pull him out have been turned to dust. If there was a way out on your own, one would think Janet Van Dyne would have found it. Will somebody just happen by and press the "Return" button? Will he sit there until the end of Avengers 4 and then get pulled out in the post-credits scene by a resurrected Wasp? If he does, will come back with super healing powers?
