Namine wasn't quite sure what it meant, or what would happen. She hoped to keep in touch with him once he left back home to Trabia. Honestly, she was unsure if this summer would really be all they would have together. Right now, being together was comforting, and she would accept that.
"Really?" Whole other siblings that she had never met? Well, possibly would never meet. That was alright, though. "I am sure they have been a handful, if they are anything like us." Her and Riku anyway. "Riku is a grown man and he has been a handful since the day we found each other!" That day he tried to mouth off to the Prince.
"Why can you not be happy now?" Sora didn't get it. So he had a brother and a family. He could accept it and move on, or accept it and move on. (Because he wasn't moving TO Trabia) Riku was acting like his life would change drastically. Sora didn't think so!
"Of course I will." Because he didn't want this brother to have any delusions that he got to keep Riku. Well, and mostly for Riku's moral support. "But...why are you so reluctant about this?" Riku's memories were some of the saddest he'd ever heard. Sora always got the impression he wished he was back in Trabia with his family, or that he knew his family. Why the aversion?
