[1967 R50/2]

I will not claim to have thought this up, but it is an interesting notion:

Baltar is a cylon ...but doesn't know it.

1. He does not have a chip in his head...yet he is somehow is getting information from the cylons. We know the cylons are at least somewhat interconnected. How would this ability manifest itself if you didn't know you had it? As a hallucination?

2. #6 keeps going on about how they will have a child. From the "Farm" episode we know how extraordinary it would be for cylons to have children and how much they want them. So her obsession makes sense in this con text.

3. Do we know that he has ever taken his own cylon test?

It is a possibility.
