Arya Stark won’t die, but her fate would be far worse. The books foreshadow, and hint Arya Stark will be sexually assaulted. I know sexual assault is a very taboo subject. George would want readers to experience violence towards children. People tend to glorify the medieval period with chivalry, and knights. In reality it was way darker. I speculate the Faceless Men would send Arya Stark to kill Euron Greyjoy, because Euron reduced Old Town into a bloody sea. The thing is that Euron isn’t someone you can stick a sharp pointed end thru. Euron is very dangerous, and he fears absolutely nothing. Not even the Faceless Men. Arya ends up underestimating her opponent. She will end up beaten, tortured, and raped. Since Arya is wearing someone else’s face. No one will recognize her, because she is no one. George said he isn’t going to kill her. Their are somethings that are far worse than death.
What be worse if she ends up being pregnant, and alone. Sorry if I offended anyone.
