Our big Ant-Man and the Wasp: Quantumania questions, and some key answers

polygon.com:

Ant-Man and the Wasp: Quantumania sets up the rest of the Marvel Cinematic Universe’s Phase 5 and 6 stories, largely by introducing the deeply weird multiverse villain Kang and his infinite counterparts as a threat to everyone in the MCU. That leaves a lot of questions open by the end of the film, as Marvel teases bits of the story to come. But Quantumania’s frantic pace and choppy editing left us with other questions, thanks to gaps in the story that didn’t seem entirely deliberate. The Polygon crew who saw the movie put our heads together after the film to talk about things we’d wondered during or after the movie, from the slight and silly to the serious and confusing. Here’s what we’re wondering at this point.

This one actually seems important to the movie’s story. There is an infinite number of Kangs, but the one booted down into the Quantum Realm by the Council of Kangs apparently did something so unconscionable that the rest of them couldn’t handle it, and Quantumania barely glances off that idea. It’s implied that he wanted to handle an upcoming crisis — almost certainly the threat of Incursions (see below) — differently than they did. And he suggests that if the heroes kill him, “everyone will die” as a result. But the allusions to his crime are deliberately vague and superficial.

We’ll learn more about this in subsequent movies, but for the moment, what we have is what Loki learned in season 1 of Loki from He Who Remains, the version of Kang who was supposedly freezing the entire timeline into a single arc before a variant version of Loki kills him. “Someone is coming,” Loki tells Time Variance Authority boss
