I mean... can I just say that I thought Arya smiling while slitting Frey's throat was really disturbing? I thought the scene where she horribly murdered Merrin Trant was disturbing. Don't mistake me for having a double standard there... The actress is an adult, she can make the decisions she wants, and she's free to of course. I just personally felt uncomfortable, but more in a way like if I were watching a video of my own adult child or something... you don't necessarily disapprove, but you sure as shit would feel strange watching.
It feels weird that I have to spell it out to be honest. I can't remember when I last had to argue against the assertion that I'm a prude or something... it was an awkward scene, and it didn't help that I felt that it was bookended by an episode that was weirdly forced and disingenuous.
