My money for the final model is Doc Coddle. The reason:
There are two people in the series who have checked others for being cylons. Baltar and Coddle. From Baltar we know for a fact that cylon detection works, that he would though never tell people the true results.
So maybe Coddle is a very much selfaware Cylon who is also the only person who is aware of all the other Cylons?

As for Starbuck… after watching Razor I cant shake the feeling that her mum was experimented on in the previous cylon war and Starbuck is the first half cylon ish thing

This one is better… SPOILERS *maybe* but it does good recaps of past episodes to look for clues

If he was a Cylon why would 6 have to seduce him to get access to the defense mainframe? Just flip his fracking switch!

I do believe the hints that everyone from the Last Supper picture is excluded. That leaves about 20 or 30 possibilities

I was thinking about Tom Zarek, being the last one. Funny you should mention him. He’s been very quiet, but it would be cool if he turns up larger than life and transforms into this awesome last cylon.

Hmm, I like that idea, I’ll just let it be, cause whatever the writers give us will be amazing… Unless it’s going to turn out to be THIS! :

And finally take a look at this and discuss :

Billy (not likely)
Admiral Cain (umm probably not)
Major Shaw (doubtful, since she was only in a spinoff movie)

Zarak’s name hasn’t come up in these posts either, or Dr. Coddle

Just trying to think outside the box. And the “clues” in the Last Supper picture, are just there to stir conversation and I doubt anyone could pull any meaning out of them about who it is.

Veiled spoilers!

I think it’s safe to say the four WE know, would have shocked her in equal proportion. The one she took time with is certainly the Final Cylon (rather than one of the four we know.) D’Anna treated this one differently:

She looked AT the faces of four, but she stepped forward and gazed IN the face of the Fifth. (As if this face was harder to discern.)

She appeared emotionally staggered, and said “You! …I had no idea… Forgive me.” She and the Fifth one reached hands to one another in penitence/acceptance.

I’ll add another crazy possibility:
*D’Anna

I wonder if the final Cylon knows they are a Cylon. I am betting that person does know, and has known all along. But you never know (can’t take ANYTHING for granted).

Starbuck taking out multiple assailants – all with military training.

The Baltar cult – a forgotten compartment on a BattleStar?

if they wanna do more episodes, what if they did multiple finales? Have like 3 or 4 different finales, each one with a different character being the final Cylon? Maybe even different resolution with respect to finding Earth.

I guess my point is that the final Cylon is as much about what role that individual plays in the greater scheme, as it is WHO the individual is. That’s what I’m looking forward to seeing most.

Really, I’m not too worried who it is, just because I don’t want to be disappointed if the revalation of who the final cylon is doesn’t provide the climactic punch that we wish for. I just enjoy the ride.

My big question is how the show will end… with leaving it open for big screen, or tie up everything pretty tight. Anything could happen… we don’t even know what year it is, how many will be left in the fleet by the time it ends.

I just don’t want some crappy ‘BSG on Earth’ spinoff ala 1980’s. And I’d prefer not to leave the finale too ambiguous.

So that’s another good clue.

I like your thinking Jim…

Are we going to see the final season this year or will they stretch it till next year?

And what about the two babies, who are half human and half cylon?

If the Final 4 are different and more advanced than the other cylons, it may be that the Final Cylon is more advanced than all others.

The Final Four have been cylons “from the start.” But the Final Cylon may have transcended from one form (human or cylon model).

*Bill Adama is HIGH on my list, since he crossed paths with the prototype hybrid.

*Sharon broke from programming (and was identified by Six as ‘the weakest model’).

*What about a Six, even “Imaginary Six?” She has asked “Are you alive?” and sought to experience love.

Here’s our biggest clue: D’anna apparently saw Tighe, Tyrol, Anders and Tory as The Four, with relative indifference. But the One shocked her. Who did D’anna offend enough to seek forgiveness from?

Yep, me and my girlfriend watch this show together religiously… So I’m pretty lucky too..

I agree, it’s probably going to be someone we didn’t suspect, I doubt Bill Adama, cause if they will make Caprica the series about the Adamas, it would be a bit of a let down if we all knew that Bill was a Cylon to begin with. On the other hand, maybe Apollo is one. He might have died in that lake? Remember? The president can’t be one, cause Six can’t sense her as being one. But the she didn’t sense Chief or Tigh being one either. So these may be different models.

I JUST LOVE THIS SERIES!

Imagine we STILL don’t know who the last person is and it’s the final season. Starbuck probably isn’t because they’ve said too much about her NOT being one. Then again, it might very well be a distraction, but I don’t think so. It’s too obvious if it is.

Gaeta is a likely character because he had such a bit role from the beginning. He was with Baltar, protecting him, feeding the rebellion etc.

Helo can’t be, because he was used to be able to give birth to a new breed of cylons. But then their child isn’t the only mixed breed. Chiefs baby is also unique, and so that’s going to play some role too.

Hmmmm… I’m getting dizzy with all the possibilities of various outcomes.

Best show by far… it’s wonderfully written and it’s just a blast!

Stephen – Baltar is by far the most interesting character on the show. I’m betting the final Cylon is not one of the obvious high profile characters (i.e. Starbuck, Apollo, Adama, Baltar, or the Pres). It’s probably someone like Gaeta who gained started to become a deeper character in season 3. Don’t flame me, just a theory

Good lord, this show is top notch all the way!

For any soundtrack fans out there, do your selves a favor and invest in the soundtracks. There are 4 soundtracks of BSG out there, they are all wonderful. Worth every penny!

One thing though, for all those who saw the minisodes with Young Adama… why was it that they have such fake BLUE eyes? I mean, they are exaggerated to the point it makes you wonder… So, in the last episode of Season 4, I’ve noticed on old Adama too that he had almost bionic blue eyes…

Sttrrrrange…

Baltar is such an amazing character and those women he’s surrounded by now, are hot!
