The scrolls of Pithia speak of a lower demon that will help them find the way to earth, or words to that effect. It's of course assumed the Cylons are the demons and Athena is the lower demon. But what if the scrolls aren't about colonials, they're about the Cylons. The Demons could be the rebel Cylons and the lower demon is Boomer, the one model 8 Cylon that didn't go with them.
Also, the last Cylon is Jacob from Lost.
