I wouldn't trust Moore to be absolutely straight about the identity of the final Cylon. He knew that who ever was revealed as the final Cylon would not have the same impact of the previous revelations. So he might have decided to use a red herring.
By the sounds of things he will certainly catch you by surprise when it happens.
The six model seems to be the only one that can alter its appearence. Do you think Cylons dye their hair or wear wigs?
Of course they don't. The sixes' seem to have some mechanism by which they can alter their appearence. Maybe they can do more than just change their hair colour.
... and why would they include the scene in which Baltar seems to be puzzled by Six's appearence if he did not want to at least plant the seeds of doubt.
Then we have Dee's strange behaviour after finding some jacks on earth ... perhaps it triggered some childhood memories.
Then of course we still need an explanation for Starbuck's resurrection. Remember she said she had been to Earth and described how beautiful it was. It may have been a memory of what Earth used to look like 2000 years previously.
Now we also have Gaeta and Zarek in need of ressurection. It might all be a clever ruse by Moore ... but we will all know for sure in a few weeks.
You must still believe in the Tooth Fairy, Easter Bunny, and Santa Claus.
There are 6 episodes left. He specifically said in his interview that he did NOT want the show to be about the identity of the fifth cylon. (ala Who shot JR?; Dallas) So, the decision was made to quickly clear the air as soon as they came back from their unnecessary hiatus. Further more, he went into the detailed logic of why they (the writers and him) picked Ellen and WHEN they picked her in writing the series. Furthermore, as proof that all of this was planned out, you can look at the picture of the Last Supper and it clearly shows hints to Ellen's true identity (see the cup on the table with the poison and Tie sitting by himself?). Lastly, last year he was interviewed and hinted to the identity of the fifth cylon and he specifically stated it was NOT a main cast member. Regardless of this fact, people have continued to wish and hope for their character to be the ONE. I think with the hiatus and all of the other crap with scheduling, they have over played their cards and hyped it to the point that you and countless others can't accept it. He specifically said all of this in detail. This is not LOST. They do not have the time to say one thing and do another. Accept it and move on.
Can I explain Kara? No, perhaps she is a cylon, but Moore clearly stated, Ellen is the fifth cylon of the original five. This could mean that there are 13 cylons and only 12 had been known. But of the 12, 5 were the original models and 7 were the series. This will all be explained over the next 6 episodes and I think after this coming weeks there will be on screen confirmation that Ellen is the fifth.
Another point in the interview that bugs me about people not believing is Earth. He clearly stated, Earth is EARTH. Not another place thought to be Earth, but EARTH. The planet we are currently residing on. He mentioned no time period so we are left to wonder if its in the distant past, present or future. We dont know. But its EARTH. PLEASE ACCEPT IT AND MOVE ON...
When asked if they found Earth Ron Moore said "They have found Earth. This is the Earth that the 13th Colony discovered, they christened it Earth. They found Earth." He never said that this was the one and only Earth or our Earth. And the phrase "they christened it Earth" seems strange to me. Like they named it after another planet. Maye one that they came from after leaving the other colonies.
