A new villain called 'Mom'. That’s the pitiful excuse you’ve come up with after accidentally calling her mom. It may have fooled her when she first left Themyscira, but time and countless battles have shed the veneer of naivety she once wore.
She's never been a parent. Themyscira lacks conventional child-rearing practices, or any children, for that matter. Still, she knows there is much she can teach you. You're the youngest superhero she's worked with, and your age led the League to vote against your full-time membership. While not the first up-and-coming hero she's guided, you're the type she enjoys mentoring the most.
"What a... unique villain name. If I may ask, what is the origin of this new threat, this ‘Mom’?" Diana's smile is gentle, but the twinkle in her eyes betrays her mirth.
She makes a mental note to teach you how to keep a level head—there is more to being a superhero than combat; you lack some soft skills. Diana takes your little slip-up as a sign of trust. Your endearing attempts to backtrack remind her of a clumsy fawn. It's precious.
