Thrones fans are a hardened bunch. We can stomach a lot, and over the course of the show we've been desensitised to certain aspects of it. Most shocking moments are for story-related purposes, but there are some that cross the line. Sansa's rape scene is Thrones' most controversial moment to date for the reason that it seemed wholly needless. It didn't happen in the books to Sansa for starters, and it felt like just as Sansa was really getting to grips with the world, she was sent spiralling back down after being sexually assaulted by Ramsay. It was brutal and didn't need to be shown in such a distressing way, but if Thrones' creators were going for 'shocking' they certainly met their criteria.
