They were going to go get some tacos and leave. lol No, I was sort of expecting them to kiss or for Kairi to start crying over him, but instead, Sora cried over Riku which I poked fun at Kairi for that. I also thought they would've gone off for a bit to collect themselves and go over a few things maybe a few flashes from their island days in the last game and a bit of their childhood to, leaving Donald and Goofy to discuss their thoughts about Riku in the last game (and to beat him down! lol), then the other two would come back and they'd get back to the story.
The other way it happened was good too...I guess. ^^
