Any theories out there? My gut says the 5th Cylon isn't just some obscure character - or even a big but not huge character like the Chief. It's got to be someone very significant. Some think its Roslin - noting her halucinations with the Cylons but I think her having Cylon blood probably could explain that. My feeling is that it's Adama - and that Lee's the first half-breed. Of course one of the cylons said that Adama was a cylon way back in one of the first seasons - but of course they didn't really know who the final 5 were themselves, did they? But if Saul Tigh can be a Cylon and go 40 years back with Adama, then there's no real reason why Adama can't either. Clearly he doesn't know - we don't think he heard the music in the season finale either - but nor did some of the other cylons apparently either. Adama did somehow have the foresight to be on a Battlestar that wasn't susceptible to the initial cylon attack though - that's kindof intriguing Overall it just makes sense to me - the final Cylon's identity has to be someone that's going to make everyone pause and reconsider their hatred for the Cylons. That to me, means Adama. Sure there's plenty of reasons one could cite that its not him - such as the mini-series when he was stuck on the ship in the radiation with the cylon who was feeling the effects of the radiation. But apparently these final 5 are somewhat different from the other cylons anyway - holdovers from the "original" cylon race which apparently dates back to Earth - so there can be ample ways to explain such issues regardless.
