The fourth trailer for season 4 of Game of Thrones is jam-packed with new footage (including a breath-takingly awesome shot of Daenerys and Drogon) but it's the new stories the trailer presents that are most intriguing.
Since this is the point where showrunners Dan Benioff and D.B. Weirs have to generate new story material to keep certain characters on the screen and certain actors employed, it makes sense that we're finally getting to see how some of these characters will spend some time. We already knew Stannis and Davos were heading to Braavos for a while. It seems that Jaime is sending Brienne to go find Arya, since Sansa is still "safe" at King's Landing. But is Ramsey Snow going to be hunting down Bran and Rickon? What happens to Bran and the Reeds? And what will Theon/Reek be doing during all this?
We won't have too long to wait to find out. April 6th, people. Mark your calendars.
