Everybody has a breaking point although she might not be showing it at all. She witnessed everybody in her family get slaughtered, friends, dire wolves included and her kin. What I saw was someone who's already crossed over and was laughing hysterically because it's become almost comically twisted that these extreme tragic circumstances occur repeatedly. She's become numb already. I still stand by my review because geezus she's seen the most at such a young age. Who wouldn't lose a part of their mind. Of course in GRM's world she's being molded into a cold blooded assassin so from a fan perspective we see her as literally a bad ass heroine in the making. From a human standpoint I'm thinking man poor girl. That's the beauty of the show. The ones who've endured the most hardship end up coming out on top or go through a redemption arc...USUALLY. Good and bad.
Littlefinger getting beaten in a duel and getting his revenge many years later and becoming a mover & shaker.
Varys - A eunuch who rose to a highly influential adviser
Danaerys - slave girl to queen
Tyrion is the most obvious.
Arya who was feisty, but an innocent girl who turned to the dark side and has more kills then some of the of the other major characters.
Boltons' felt slighted all those years under the Starks and are now the Warden of the North.
Jaime has turned 180 especially after getting his hand cut off.
There's never been a story like this told before where each character and house could have their own entire series pretty much.
PS: Wonder why they had three different actors play The Mountain...
Marcus Aurelius: Tell me again, Maximus, why are we here?
Maximus: For the glory of the Empire, sire.
Baked, not fried... the healthy choice.
