I'm going to vote for Xpl. He's been one of the more inactive players (I cannot speak myself, but I can however say that I was, and still am in the midst of a particularly gruelling exam period, 7 down, 3 to go [and a Rush concert tomorrow])
Furthermore, my reasoning upon Xpl is that I was attacked by a woman on Night 1. Also no kill last night suggests it is one of the quieter players.
