Arya Stark getting stabbed by the Waif was one of the biggest surprises in last episode [The Broken Man] of Game of Thrones. As we saw, she barely managed to escape, then jumped into the river and stayed underwater for some time for her attacker to presume she was dead. We then see her walking through the streets of Braavos, being in terrible pain from her wounds. While this didn’t please the fans, many are suggesting that Arya’s actions could be a part of an elaborate scheme. Check out this theory by Redditor iPlayNL:
“We are led to believe Arya got stabbed, however there are some problems with what happened this episode. First off, Arya seemed different from the start. Her scene with the merchant, her walk all seemed very confident, which is unusual after the events this season. … Also, where did she get the money from? Why was she not carrying Needle [her sword] with her? How come after all she knew about the faceless man she just stood there on a bridge not paying any attention?”
Redditor passingwisdom thinks that Lady Crane (theatre actress) may have helped Arya:
“We can assume she knows enough from training to figure the waif will attack to the body. So I believe she has 1 or more pigs blood pouches around her body. She knows where and how to do this because last episode… she saved the actress. The actress then provided her help to make the scene on the bridge large and realistic. … She then leaves the water and leaves a trail of blood…. to lead her [enemies] to her. Expecting an unarmed (because she choose not to show needle during the fight scene) and injured girl; they will instead walk down a dark alley and be met with an uninjured girl who knows how to fight in the dark and carrying a sword.”
Check out this shot from season 6 trailer. It looks like she is deliberately making a trail of blood.
And some believe that it wasn’t Arya who we saw on the bridge but Jaqen H’ghar disguised as Arya. froschkonig writes:
“That wasn’t [A]rya. She would have been carrying needle. She wasn’t aware that [Jaqen] said not to make her suffer, so making a big show of her suffering doesn’t make sense. It was [Jaqen] testing the waif, and by stabbing her in the stomach and not just slashing the throat, she disobeyed orders just like arya did. [Jaqen] is gonna lay some faceless justice down.”
Last episode’s events have definitely made Arya’s storyline super interesting and below shot from the episode 8 preview shows her doing some serious parkour. So, the general consensus among the fans is that she will be fine by the end of the upcoming episode [aptly titled ‘No One’] and hopefully be on her way back to Westeros.
