Somehow the other Yuugi knew about that, which shouldn't-- shouldn't have been possible! Yuugi hadn't told anybody yet, and if he did tell anyone in the future then he felt pretty certain it would be Jounouchi and no one else. Maybe Anzu and Honda. Maybe.

But not anyone else.

So how did the other Yuugi know, unless...?

Yuugi abruptly pushed himself to his feet and took a few steps away, needing some distance as he freaked the heck out sorted his thoughts.

"This doesn't make any sense," he stammered after a long moment, clenching his fists so his hands would stop shaking. "You said that you're the other me and that we've had a conversation like this already, but the other me doesn't talk; he's never said anything before and I don't know if he can hear me either," he added in a rush, seeming not to realize that he was referring to his hypothetical other self as being... well, not hypothetical. "So I don't know how that could be you." And...

And if the other Yuugi knew how Yuugi felt about his friends finding out all this crazy stuff, then what else did he know about Yuugi? The thought alone was enough to make Yuugi feel a little sick and scared and vulnerable.
