Why Ellen?
There?s a certain logic to it. I sort of figured out early on that I liked the pairing of her and Tigh. [I liked] that there was something deeper to their marriage and deeper to their relationship, that it was literally a relationship that had transcended time and space, that it was very ancient that had gone on for a very long time. It was something that was [mentioned] in the pilot for ?Galactica.?
When did you make that selection?
It was somewhere in the course of the third season [that the possibility was first raised.] We killed Ellen early that season and we didn?t have an inkling of that at that point. But at the point that we killed Ellen, around the same time frame, I was starting to come up with the idea that there were five Cylons that had yet to be revealed.
At the beginning of the third season, Baltar had gone to live on the Cylon base ship for a string of episodes. And it was really that plot move that threw into relief -- well, once Baltar?s over in the Cylon world, why wouldn?t he see all 12 of them? How could we get around that and parcel that out? Then I had this idea, well, what if it?s not random? What if there?s a meaning to the fact that we haven?t seen the five of them? And that?s how the Final Five became part of the mythos.
Over the course of the third season, Ellen came and went in my thinking in terms of who the final five were. It probably wasn?t until we settled on the final four that I knew it was Ellen. When we got to the final four -- Tigh, Anders, Tory and Tyrol -- then it felt like, ?and Ellen has to be the fifth.? Because Tigh being revealed as a Cylon was such a profound shift in that character, such a big leap for the show, that it felt really natural that she was also a Cylon.
And he had killed her for collaborating with the Cylons! There were layers and depths to that I felt were really fascinating, about guilt and blame and memory and responsibility, and I just really liked the way that all tied together.
So we will come to know, in this next set of episodes, who knew that Ellen was a Cylon, and that will play out in what?s coming?
Yes.
So we?ll see her again. Does she figure prominently in the season?
I don?t want to give too much away, but it won?t be the last time that you see Ellen.
One place my mind instantly went, on a fan-trivia level, was to that opera house vision that D?Anna has. She says to one of the Final Five, something like, ?I?m sorry, I had no idea.? Did she say that to Ellen?
I think the intention of that -- we had a conversation about that in the writers room -- [once it had been decided that Ellen was a Cylon] the intention was that [the one D?Anna spoke to] was Ellen. When we wrote the line, we didn?t have a clear intention, but later, when we?d decided [on all the Cylons], I think the feeling was, that was Ellen.
