I'm wondering why Lang or Pym didn't shrink the ant back down to normal size at the end? Was Cassie secretly keeping him as a pet? You'd think she'd be terrified of the thing. And apparently the special effects crew haven't made any of the ants quite realistic or like how ants actually look in real life, because when magnified like that, they would look terrifying and creepy, and they didn't want to scare kids or adults. They're all slightly more stylised ants.
