Five possibilities for the final Cylon
The writers of BSG have a huge challenge in choosing the final Cylon. They already shocked us with the season finale last year when we learned that Tigh, Chief, Torre and Sam are Cylons. Who could possibly be more shocking than that? The final Cylon can't be some character who suddenly appears this season and has a major role, just so he/she can be the final Cylon. I truly doubt it's either Pres. Roslin or Adm. Adama because that might be too over-the-top and therefore unbelievable. Of course, the writers could easily take us there over the season and make it shocking, yet believable. (These BSG writers really do rock, don't they?)
So, I thought about it. And here are the five characters who would make a shocking final Cylon:
Zak Adama - This is Adm. Adama's other son. The one who was engaged to Kara Thrace. The shining star in the Adama family. He died during military flight training because Starbuck approved him to fly when he wasn't ready. Zak comes up now and again, but mostly when Adm. Adama looks at photos of his boys. The reason he's included is because his return as a Cylon would rock the worlds of Lee, Kara, and Adm. Adama. Why do I even think about him? It's something Lee said to his dad three episodes ago when they were wondering whether Starbuck is a Cylon. He asked his father whether he'd want to have Zak back, even if it meant he was a Cylon. Foreshadowing?
Billy- President Roslin's former secretary, Billy Keikeya, was a beloved character up until his demise in "Sacrifice" (Season 2, Ep. 16). He was in love with Dualla, remember? Dualla went on to marry Apollo--although it appears that marriage is over. Billy is kind-of a long shot and he died so long ago that his return might just confuse people. Still, he was a great character and it would be nice to have him back. He was such an innocent soul that being a Cylon would be a real shock.
Gaeta- Felix Gaeta is looking like a strong possibility these days. He is filled with hate--for Baltar, Starbuck, and especially for Cylons. He is heavily relied upon by Adm. Adama and perhaps we'll see some storylines in the future where Gaeta gets even closer to the admiral. Gaeta would definitely be a self-loathing Cylon. But, Tigh is already revealed. He's self-loathing and is very close to Adama, so there may not be a need for another Cylon so close to the Admiral. If he's not a Cylon, I have the feeling Gaeta is in for something big (maybe death?) this season.
Lee Adama- We know that Adm. Adama was not present for the upbringing of his two boys. Maybe he wasn't even there for their births. So... they could be adopted, right? The realization that Lee is a Cylon would be frakkin' huge. He's in love with Kara. He is finally on good terms with his father. It would be heart-breaking, really, to learn that he's not human. I want to cry just thinking about it.
Starbuck- It's impossible not to include Starbuck in this list. Where did she go for two months? Why did her Raptor return in perfect condition? Obviously the writers are trying to keep us wondering whether she is a Cylon. There is definitely something special, maybe even mystical, about her. Why has she always painted pictures of the nebula? I'm starting to believe that she is not a Cylon, but she cannot be discounted at this point.
