Season 6, Episode 6: Blood of My Blood
Arya doesn’t kill Lady Crane. A Girl has A Conscience.
Season 6 saw Arya paying the price for her defiance of Jaqen’s assassination request with her sight as the Waif trains/beats her on the daily to get the girl in line and make her the best assassin she can be. After enduring such harsh punishment and training, you would think that maybe Arya is committed to the laws of The Faceless Men. That she would just do what she was told and kill who she was told to kill. Like a good girl! But her devotion to Jaqen and The Many Faced God is tested when she is ordered to kill Lady Crane – a kind and charismatic actress starring in a play depicting the death of Ned Stark in very unflattering light.
When Arya is spotted backstage after the show, Lady Crane takes a liking to her and exposes herself as…. not an awful person deserving of death. When Lady Crane goes for the rum Arya has poisoned, Arya knocks it out of her hand and tries to pin it on a fellow supporting actress. So Lady Crane survives, if only to nurse Arya back to health after she’s stabbed by the Waif two episodes later.
What’s telling about this is that this is he moment where Arya knows she cannot deny her noble Stark side no matter how hard she tries. She is a character that operates from the gut, has a very clear definition of right and wrong, and acts accordingly. She is not A Girl who can simply follow orders and kill blindly. Arya Stark kills for a REASON, goddammit. And she’ll exercise her judgment to let someone live just as quickly as she’ll exercise her right to avenge.
