I really enjoyed it, not so much for her part in it as for his - she thinks she's seduced him into telling the truth, and he reveals that he's known what she's up to all along and went along with it anyway, because hey, this way he gets to sleep with her.

At that point, I stopped caring that she would Never Do That, and that he had never shown any sign to be in lust with her before, because that was just Octavian at his Magnificent Bastard finest.
