[Riku's heart tightens with guilt at Sora's words. He hates thinking about that time. He hates his fifteen year old self a little. But he's moving past the guilt now. Or trying to. Guilt's a backstabbing, wily, thing.]

Kairi's fine. She's asleep. I doubt she's dreaming. She had a hard day of training.

You'd be proud of her if you saw her.

[Okay, so he's regaining memories it sounds like. He's had multiple dreams about them. That's good. And Sora's heart is strong, he's confident that Sora can fight this brainwashing.]

And I'm okay. Those dreams you're having now? They took place a couple years ago. I... I'm not proud of what happened, but we're okay now.
