Oh, that again. The events of Castle Oblivion always left Sora a bit unnerved. While he had been informed of what happened there, he knew there was no way he could get every detail of it, not to mention he had no sense of what his particular experience of it had been. His inner thoughts and feelings during that time were gone forever, and seemed to only come back in vague phantom emotions when he was around someone who had been involved in it.

He knew his memories had been a large portion of that incident, so it looked like Axel had gotten a glimpse of them. The fact that the Nobody knew about his past was a little weird, but there was luckily nothing to hide there.

Axel's next words made Sora stiffen up as he stared at the man. "What do you mean?" he asked quietly. He could be implying any number of things, but either way, the boy got the feeling that it was serious.
