[Kairi's breath catches in her throat. The question throws her and so her only immediate answer is the truth.]

I don't know exactly.

[But it's not good enough, and it would be lying to leave it at that.]

When I woke up in Hollow Bastion, Sora disappeared. There was a man there, with white hair and yellow eyes. He called me princess.

[Like Riku's shadow. Kairi suppresses a shiver.]

And then you appeared and told us to run. But you weren't really there. You were a part of him, somehow. You held him of, and we left, me and Sora's friends.

I pulled Sora back and we left for Traverse Town. Sora was going to go back to find you but... You'd lost your heart, Riku.

[She stops, her voice quavering. But she's not done. She can't leave it there.]
