Oh, she does live in a world of superheroes (or at least one superhero). Miss Bouncer/Amelia White (Venya’s inflatable, floatable superheroine) is a friend of Irene’s. Amelia has asked a couple times, but ultimately Irene thinks her “powers” are useless for fighting crime. They aren’t really under her control, and although preliminary experiments show she can’t pop, Irene’s not willing to test if she’s truly indestructible. For now, she’s happy being a consultant to the literal biggest superheroine in town.
