In the Temple of Five, #3 (D'Anna) seeks to see the faces of the Final Five. Cavil says "That can't happen" and tries to shoot her. Later she is boxed for her quest (and also because the actress is only contracted for so many episodes, but we'll ignore that.:-)

As she enters the projection, she looks with some surprise at the 5 robed figures laid out before her. Curiously, there are six drapes, but they stand on only 5 of them, leaving the one on her left empty. Then she approaches one with a look of shocked recognition and issues the apology:

You... Forgive me I...I had no idea

(By the way, in a nice irony, as she gives up everything to see the faces of the Final Five, two of them are outside, getting shot at by her own Centurions.)
