It was pretty weird. Kairi should have tried to find out more...

Kairi continued to look at Sora strangely. She still wasn't following what he was saying, and she could tell that even he was having a hard time trying to explain to her. "A... part of me?" She had been feeling like something was missing... "Ah... how...?" Literally? Figuratively? ... no, no... but how could he mean literally? How would they have even gotten separated if it was literally?

The more she thought, the more confused she got.
