[Sora doesn't even try to hide his shock when Riku says that it's been eighteen months. Eighteen months. That's...well, a really long time, when he doesn't even feel like he's been away from the islands a full day.]

Er...doubles?

[No, no she did not mention that.

But right now, there's something that Sora's a lot more worried about.]

Wait, Riku, just forget about that for a second!

Look...I know it's been awhile for you, but it's only been a few hours since the islands got attacked for me. And, well...

[He hesitates, closing his eyes for just a second and trying to think.]

Well, I still don't really understand what happened.

[He doesn't even have to say that he needs help - that he's looking for answers. The look on his face does that well enough.]
