As for the current subject a few seem to be bringing up, I suspect there is a possibility of a third party but I would suspect them to be limited in their abilities due to the lower number of participants.
But this is something that will never get answered on the first day, barring an idiot blowing his cover, so I don't think it is something that should be given too much thought at this point.
I am actually more interested in hearing what the possible hidden message was in the flavor the theprof came up with.
