Its my understanding that during the English Middle ages such debauchery wouldve gone on. Us English have a whole load of Plantagenets to feel bad about.

So, when you first knew Cersei and Jamie were brother and sister and knocking boots (so to speak) were you

I personally fell in the shocked category a bit more, especially when I saw King Joffrey in action.

I'm happy with either opinion. I ask out of mere curiosity and I shall place no social or moral judgement upon your answers
