A Moment that Kairi Talks about Sora: "No… Sora’s in danger because of me."
I just always found this scene interesting, how Saix says “You’re the fire that feeds Sora’s anger.” and I think it’s really the first time Kairi realizes that she can be used against him. She’s seen the drawing in the secret place, so I think it’s fairly obvious she’s aware of his feelings. Kairi doesn’t want to be the reason for Sora getting hurt
She of course doesn’t happen a weapon yet, but I think this scene is going to be a huge motivator for her to make sure she is always able to defend herself so a situation like this can never happen again.
