Warning: Spoilers for all aired episodes of Game of Thronesahead.
In the latest episode of Game of Thrones, "The Bells," we saw firsthand through Arya Stark just how much destruction Daenerys Targaryen's attack on King’s Landing caused. Viewers followed the trained assassin as she ran alongside thousands of innocent civilians trying to get away from Drogon's fire, and Arya nearly died herself. She saw all of the massacred people in the streets, along with buildings falling left and right, but she managed to escape the city in the final moments of the episode.
This wasn't the first time we saw Arya use her intense survival skills to avoid death in a battle this season; she memorably survived the Battle of Winterfell and saved the Seven Kingdoms by killing the Night King. So of course, the next outcome fans have started to speculate about is whether or not she will do this again by killing the Khaleesi.
Since it looks like Daenerys has fully become the Mad Queen, many believe she has to be killed in the finale, and one new theory argues an interesting way Arya could do it. As reported by Inverse, Redditor hoowuurd believes Arya will use Grey Worm's face to commit the act, after she and Jon Snow decide they must kill both the Unsullied leader and the Mother of Dragons. As we saw during the siege of King's Landing, Jon's perspective changed once Dany and Grey Worm began killing again after the city surrendered, so it wouldn't be a stretch to believe Jon knows they need to end another possible reign of a tyrant. And now that Missandei is dead, there's no reason for Grey Worm to ever leave Daenerys's service.
"Arya will use Grey Worm's face to kill Dany, and set it up to look as if either Grey Worm killed Dany and then himself, or just flee the scene and leave it a mystery to the realm," the user argues.
We're sure many fans would be behind this move, as it would mean we would get to see Arya use what the Faceless Men taught her one last time. She brought faces back with her to Winterfell, as Sansa Stark discovered in the season 7 episode "Beyond the Wall." We haven't seen Arya use any faces this season, and it seems a shame to end the series without at least one more trick like this.
We don't see where Arya is headed once she rides out of the chaos in "The Bells," but she's probably going to find Jon. And even if Arya doesn't actually kill Daenerys, we can bet that she will have a huge part determining where Westeros goes from here.
