The Final Cylon is People
According to last nights big reveal, Ellen "The Cougar" Tigh is the final Cylon.
I say not so fast. I have been expecting some reveal like this for a bit as red herring: I think Ellen Tigh is a Cylon, but not the 5th. Rather, I think she was an aged #6. That would track with Tigh's visions of six as Ellen and his attraction to Six.
That said, I don't think it's Starbuck.
I am in for Tom Zerrick.
