this would have to be the first time I have ever seen a multi expose himself by accusing someone of being a multi.

It would fit though. It explains why he was so jumpy at accusing them of being multis (his teammate missed a turn so the guys on the other team are the same person? What?!)... after all, if he could bust someone for being a multi no one would bother accusing him of being a multi. And it would explain the odd proceeding of posts in this thread between the two.
