Even though i was still a couple seasons behind at that point i remember the massive amount of speculation about who the "last" Cylon was after the first 11 had been revealed. I think they pushed that the big draw for a significant amount of the last season. (I still don't know myself who it is, or if it really was the last Cylon, though i expect i probably would have noticed a significant vocal backdraft if they'd "cheated" on that.)
