“Well, I think one of the things that we've set the seeds for in both movies — and I think particularly in Ant-Man and the Wasp — is Cassie Lang, Scott's daughter. In the comics, she goes on to be a hero in her own right, so I love the idea that in this movie we see that moment where she covers for Scott and stands up to the FBI agent. We see a little bit of her father's personality in her. I'm intrigued to kind of see what the future holds for Cassie.”
Cassie becomes Stature, the size-changing member of the Young Avengers, in the Marvel Comics Universe. After her apparent death and resurrection, she teams up with her dad and becomes the ant-themed heroine Stinger. Those later stories are the ones that have Reed’s attention when it comes to Cassie possibly becoming a hero in her own right on-screen.
“It's possible,” Reed says. “I mean, it really is. There's some interesting stuff in the Nick Spencer Ant-Man comics where I think they're living in Miami in the comics, but Cassie is in high school, and she's having typical sort of issues that high school girl might be having, and I like the idea of Scott Lang sort of having to deal with Cassie at almost any age. I like that dynamic a lot.”
