Nothing really extraordinary in this, but some little details that are spoiler protected:
Knights of the Vale in a scene being shot in Iceland, and it seems Brienne will be in that areaboth with a new sword and new armor. And Arya will be there as well in Iceland, though weve known that previously. Were guessing that Brienne and Arya might somehow cross paths. A glimpse of whats certainly Mark Gatiss as Tycho Nestoris in what must be the Iron Bank of Braavosshowing that Stannis and Davos will be going there directly, apparently, as a means of fleshing out what Stannis is doing while the the end of the season awaits his arrival at the Wall. Some more glimpses of Oberyn twirling his spear around like a drum major leading a band (no, sorry, cant get behind this sort of stuff) and it seems that Gregor will start the duel with a helmet on, though we can see hell lose it along the way. Some more glimpses of the Meereenese throne room set in the Belfast studio, as well.
