Peyton Reed commented on the differences between Cassie and Scott Lang, particularly after the five-year period of the blip when he was in the Quantum Realm. As he tells Jeremy Mathai:

“We inherited this great concept from the events of ‘Endgame,’ which is, Scott’s lost another five years with Cassie. She’s no longer a little girl. She’s a young woman. She’s 18 now. This movie sort of starts to tell the arc of her becoming a hero in her own right, but also the idea that she’s not her dad. She has very different ideas about justice and what are the issues at hand, and the problems the world was facing. And she’s quite critical of her dad. ‘You’re signing books, man. You should be out there doing this other stuff.’ And that felt like a sort of real dynamic between a father and his young daughter.”

Scott was sort of a reluctant superhero in the first place, and dining out on your fame after, you know, saving the world isn’t exactly a surprise or anything terrible. Still, Cassie is young, and she wants to make a difference. It stands to reason that she’d want to see her father use his fame for something more important than a memoir. 

“Ant-Man and The Wasp: Quantumania” will hit theaters on February 17, 2023.
