Pantisilea

Funny I just saw this, but I just commented on this on the Funniest Moments thread...not that it is funny.

I always assumed it was Cesare that killed her after waking from his drunken stupor and realizing the night of debauchery he had.

I though it was deliberately ambiguous. If they wanted us to think that she had been killed by Cesare 100% she'd be naked on the river. But she's dressed. So the fisherman could be wrong and anyone (Cesare, Lucrezia, Giulia, someone else altigether) could have killed her after Cesare whipped her (or whipped her again to death). The meaning here is that unlike Juan, there won't be an outcry for Pantisiliea, or a long investigation, or people wondering who killed her for centuries. She's a maid, and so just another unknown in the river. We have seen her through several episodes, and so have these people, but unlike us they don't care what happened to a maid because they have thousands to replace her.

I know this is an older post, but here is my response.
If I remember right, there was an episode in Season 3 that had Cesare admitting to his soldiers that he killed her. I wish I knew which episode, though...
