Hmm.
I keep getting the urge to be clever and try to be a higher level player than the others, but I am not so smart so I won't go making guesses just yet.
Freeky, it's alright. First round is always a guessing game*, and the talkiest people are naturally the most suspect. Pointing fingers this early on is meaningless.
Going by what I know of game theory, I think out best option at this point is to just talk and think, and leave guesses until later in the round.
*ETA: More of one than usual, rather.
