After surviving an assassination attempt by Waif, Arya Stark is free of her ties to The House of Black and White. The actress she was supposed to assassinate winds up saving her and Arya finds herself experiencing some wanderlust. So what is west of Westeros on Game of Thrones? Arya is planning on finding out.
Lady Crane nurses her back to health by bandaging her stab wounds and feeding her some soup. (Incidentally, this seems like too easy a fix for what must be massive internal bleeding, but milk of the poppy makes everything better, right?) The maternal energy really does do poor orphaned Arya Stark some good, however, and she begins to express hope and energy speaking with Lady Crane.
"Essos is east and Westeros is west, but what's west of Westeros?" she asks the actress, who claims she doesn't know.
"Nobody does," Arya presses. "It's where all the maps stop."
This is a childlike curiosity we haven't seen since in Arya since Season 1. When Lady Crane suggests that perhaps west of Westeros lies the edge of the world, Arya replies, "I'd love to see that."
As far as George R.R. Martin has told us, there is nothing west of Westeros, other than The Sunset Sea. "No one has ever crossed the Sunset Sea to learn what lies on the other side," he's been quoted as saying. He also added that the Westerosi believe the world is round, while some of the commoners likely still believe the world is flat.
The westernmost landmass, as far as we know, is The Lonely Light, one of a cluster of 13 islands that are part of The Iron Islands. In the book A Game Of Thrones, we learn that Brandon the Shipwright, who was once King in the North, sailed across The Sunset Sea and was lost. It's possible that the world simply stitches back together at the edges of the map, like Earth does, but that no one has ever made it across The Sunset Sea. Or, there might be another landmass altogether that George R.R. Martin is hiding up his sleeve. There would be less surprising reveals in Game of Thrones than a whole other tribe of indigenous people we didn't know existed.
Arya's curiosity is cool and all, but we need Arya Stark back in the North, STAT — especially because Sansa and Jon could use just about every hand they can get as they take on Ramsay to win back Winterfell. So though figuring out what's west of Westeros is temping, let's not forget that The Girl has a name — and a home, OK?
