Game of Thrones always has a couple of topless moments throughout it's episode. The first one was pretty ruthless and sadistic.
#1 Joffrey has a prostitute beaten sadistically
Joffrey's uncle sends him two prostitutes to have some fun since he's been running mad with power. Instead of Joffrey enjoying the moment he turns on the prostitutes as well and displays his sadistic nature to torture other. He has one prostitute beat the other one relentlessly with a whip and stick as points his bow and arrow at the first.
#2 Melisandre strips naked again but this time while giving birth to a black demon
Melisandre seems to get naked in every episode of Game of Thrones since she's been introduced, but this time she freaks everyone out by first displaying a pregnant belly and then giving birth to a black demon.
