Oh, right. I actually found that one of the least bit convincing twists of Rome, not just because a) my inner historian groaned, and b) it seemed at the time to be a result of the following tv writer thought process: "One of the big shockers in I, Claudius was the Caligula/Drusilla incest, so we better get some incest here, too", but because c) the way it came about seemed singularly unconvincing. I mean, I can buy Octavia is in love with Servilia and influenced and acting out anger about Atia and what not, but the step to "you know what would really piss off your mother who killed your husband and would maybe get me a secret, honey? Seduce your brother!" just was too bewildering.

Mind you, I found the scene where he finds her in full self-loathing punishment and forgives her and takes her home very touching, but otherwise that whole storyline just had me shaking my head.
