If you have not seen Sunday night's kickass season finale, STOP READING NOW. (But come back after you see it, because you will have questions)

*MAJOR SPOILERS*

Battlestar Galactica executive producer Ron Moore answered a few questions from a reporter at Pittsburgh's Post-Gazette that clear up some of the confusion from last night. For instance? Yes, they are Cylons. Chief, Saul, Sam and Tori heard the music when they reached a certain point in space, signaling their awareness of who they are. Moore says, "These are four of the final five, which puts them in a separate category from everybody else." Who is Cylon #5? Moore doesn't say. But he does promise that, next season, we'll get to discover the backstory for the new Cylons as they try to figure out how this could happen.
