True - had Hank been Ant-Man in the first film, then Cassie wouldn't be a superhero yet (she'd only just be getting introduced if this was Scott's debut, so she'd be a preteen). Though she'd probably also be seeing more usage in the comics because Nadia probably wouldn't exist if Hope wasn't in the movies... might even have got the solo book Nadia got (which was originally pitched to DC as a Bumblebee series).
