As Arya settles into life in the House of Black and White, she stumbles into a huge chamber filled with faces. These are all of the identities that the Faceless Men of Braavos can take on to carry out their assassinations, and naturally, with so many faces, one or two of them are pretty familiar. So it is that we see those likenesses of Thrones showrunners David Benioff and Dan Weiss, because if its your show why wouldnt you sneak in a sly appearance. Further to that, the face Arya actually touches belongs to the mother of Barry Gower, the shows prosthetics supervisor.
