i have not figured out the "head " characters exactly but i'm pretty sure i get the whole has happened b4,will happen again" stuff. i expect both human AND cylon over and over get nuked by the other.each time there is a final five(group of maybe scientists that construct some kind of ressurection technology and have it floating out in sopace somewhere. the enemy eventually tracks down this one planet where they are and nukes it. the 5 scientists also decided to clone another 7 or so. theythemselves would probably see this as creepy but they want to keep there population going.
so maybe cavil and the other "bad' cylons track down the new planet where the "good guys" evntually find and nuke it. but the 5 were ready .maybe in the end there are countless adamas,lees, helos,president, etc. gaahhh, i forgot about the mechanical cylons. forget it, i'm just gonna watch. maybe another fan can help with this.lol. i DO think there is a plan though. i think they've pretty much had it in place from the start.
