I think you guys might be on to something.....Kara was the only one able to fly the cylon raider, her mother told her she was special.....what immaculate conception???LOL She is the best pilot in the fleet, Leoben is obssessed with her and also seems to point her in the way of her special destiny, and she miraculously returns from the dead at the cliffhanger....Anyway there are many things supporting the conclusion that if she is not a cylon, she is a link between the two species...
I also read from your posts that cylon males are sterile, but there also seems something pointing to the fact that the final five are special cylons that not even the known cylons have ever seen. Whats the common ground between Tigh, tyrol, Tori and Sam anders? Tyrol and tigh are in the colonial service. Tori was a member of Roslins staff in the beginning, and anders....a sports star and leader of the civilian resistance. I can see common ground in some but not in others. They all have miraculously survived--Tyrol and Tigh because Adama did not beleive in computer networks and Galactica was the only ship that could fight, Tori survived that initial attack on colonial one when lee thought he fooled the cylons with the hyperdrive generators in the hold---although he said he could not beleive it himself because in training the cylons saw right through it. Anders on caprica surrounded by cylons and his group survived and made it to galactica because Kara (as I said, shady in her own right) insisted on a rescue mission to get them.
It seems that the whole plan was to have them survive and put them into key positions--Tigh XO of galactica, Tyrol-leading deck hand and popular amongst the enlisted crew, Tori made it to presidents aid after billy bit the big one. Anders-sports star and leader of the civilian resistance and popular amongst the civilian population. But on realization of who they were they did not turn on the colonials, but sided with them at the cliffhanger......What? Program click (pulling a boomer)and they seize control of the galactica and the presidency?????
Just my two cents worth!!!LOL
