The scenes between Regenerated Octavian and Livia were just... yeah, creepy. I am sorry that we did not get to see the battle fo wills (and ti would have been spectacular) between Atia and Livia.

Polly Walker had definately gained a little weight and had a softer face for the second season (and looked a LOT better, I think). There was some speculation that she was pregnant, but no one was able to confirm or deny.
