Game Of Thrones Season 6: 8 Things You Might've Missed In 'Blood Of My Blood'
7. Mercy And The Iron Throne
Sticking with the play, or at least moving backstage, Arya gives her name as Mercy when asked by Lady Crane. Much like the play itself was lifted from The Winds of Winter, so too is Arya going by the name Mercy.
It could also be said, as well, that when Arya is talking about how Cersei would feel, she's not only accurate given the rage we saw in Cersei when Joffrey died, but also talking about herself and Ned's death - especially with the line: "I have to go. My Father's waiting for me."
The other Arya moment that wasn't easy to catch was this nice visual, as seen in the image above, which frames her as though she is on the Iron Throne. A moment of foreshadowing, perhaps?
