When asked if the relationship between Diana and her mother would be explored more in the future, Wonder Woman herself, Gal Gadot, said, "Of course; the mother and daughter relationship is always a beautiful but complex relationship. I think that there's a lot more to explore."
Connie Nielsen — who portrays Diana's mother, Queen Hippolyta — added, "[Wright and I] got to do more in Justice League as well. As sisters as well. Kind of badass as well. We can't say much, but ..."
That's when Wright chimed in stating, "And more of the story, you get some of the history."
*screams with excitement*
