As Kai talk about her urge to return to the ocean, Tidas could help but be hurt. He didn't want her to leave, no matter what. Though his parents could see the look of sadness in his eyes and his mother spoke up saying "For now Kai focus on your child and preparing things. You have our full support, hopefully your and Tidas's union will bring our people together. Worry about your urge to return another time. Your child comes first, just try to focus your mind on that..." With that lunch was finished and the King and Queen had to get going.
They made sure to hug both Tidas and Kai, though as the Queen hugged Kai she whispered in her ear "Be careful with your lower body, if Tidas is anywhere near as big as his father I am sure you dealt with a lot of pain. Just focus some magic down there, it will open up eventually"
