Well.. Kia didn't mean it literally. "Not literally.. but I completely advocate payback in general for her if she does anything hurtful to Juto." After all, Sheri's family was her family and vice versa. They were just that tight. "We can always lock her in the Playground with the safeties on and scare the shit out of her until she realizes the error of her wicked ways."
Or give her a mental breakdown. That was highly appealing for Kia.
