This is one of the clearest pictures to date of Gwendoline Christie as Brienne of Tarth, and you can see just how remarkably transformed she appears. The stiff collar helps give her face a heavier, jowlier appearance, the hair also seems to make it all a bit heavier—tremendous work by makeup, costuming, and hair.
Also, you can see Lord Rickard Karstark at the bottom end of the image, apparently talking with (or arguing with?) Brienne about something.
