Razor made me mostly eliminate Cain. When her story was untold, there was more mystery to it, particularly about how her ship was the only other one to survive the attack. Adama, whose ship had on it 3, and possibly 4 of the final 5, was obviously planned from the start to survive. We now see Cain's story as just luck, and her determination to order the blind jump.

The final 5 and final one are unlikely to "lead the cylons against Adama." They are not on the same side as the 7 Cylons who waged the war. They are on their own side, and it seems to be much more pro-Adama, in fact they are the reason Adama is there.

If Cylons won't blast her, why did Gina put a hole in her head? Why did metal Cylons shoot at Anders and Tyrol, and even hit them?
