so, back to arya and the hound. somebody explain the story arch of that relationship. I'm confused why her character just left him for dead instead of putting him out of his misery. I mean, at first blush, the hound is a heartless eff face that takes helpless Arya "prisoner" for self gain. but then, the show chooses to develop their characters and their relationship over an entire season. by the end, the hound's character has developed into a likeable father figure and arya embraces him. this development culminates with her mending his neck wound 'n such.
and then, in the last episode when he's facing death, she's just like, ahh, eff off, robs him, and leaves him for dead.
I guess it just shows that the hound had successfully molded her into a survivor, devoid of any moral fortitude (i.e. robbing/killing the guy who took them in).
