Avengers 4: 9 Things We KNOW Will Happen
6. Ant-Man Returns
Given a cursory line to explain both his and Hawkeye's absence in Infinity War (the pair took deals with the government so they could visit their families whilst being monitored - check out Lang's ankle monitor in the Ant-Man & The Wasp trailer), Ant-Man is back in Avengers 4.
We know this thanks to the previous point's set leaks. Paul Rudd is right there on set as part of the same crew alongside Stark and Cap, but interestingly, he's wearing his suit from Ant-Man & The Wasp.
It's discernible from the red shoulder pads vs the original design's silver, and lets us know that it's the post-Civil War version of Scott that helps reform The Avengers (or whatever's happening here).
As if his arc wasn't layered enough, we now have an ex-con dad who went back to a life of crime, helped stop a maniacal tech boss, intervened in a large scale superhero brawl and then took a deal to return to his family - only to get lost in a time-travelling scheme to reunite the Avengers against a supersized purple alien.
As you do.
