[Riku knows she's right, of course, Sora was his best friend and he's going to carry that around with him for the rest of his life—but it still hurts to hear. Talking about it...is something he should do, he really should, but he's having a hard time making the words come.

He can let Kairi talk, though. He can be there for her, at least. It's what Sora would have wanted.

So he just wearily nods, silently agreeing that he'll always be with them.

He can comment on the first part, though, in a low, gruff voice. Because it still makes him angry to think about.]

You couldn't have done anything.

[...Which comes out harsher than he'd intended. He takes a deep breath before speaking again.]

Sorry, I meant—fighting wouldn't have helped, it just. That thing just touched him. There wasn't a warning, there was no time—no chance to do a damn thing.
