The mysterious character's identity was finally revealed when the acclaimed series recently resumed its fourth season.
Moore told the Chicago Tribune: "There's a certain logic to it. I figured out early on that I liked the pairing of her and [Saul] 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. ... And he had killed her for collaborating with the Cylons!"
Moore also explained his reasons for not drawing out the Final Cylon mystery for longer: "We wanted to shock, and we wanted to change the game plan. I knew that I didn't want to reveal the final Cylon at the end.
"I just felt like that was too much [pressure] on the end of the show, and I didn't want to have to answer this question [then]. And I didn't want the show to devolve into, 'Who's the fifth Cylon?'"
