Well we're also gonna get Tyrion traveling there, and I wouldn't be surprised if they deviate a good amount from the book story there because it really wasn't all that interesting until him and Jorah got captured, and even then not that interesting. They'll have a new angle to look at shyt at with Victarion and the gawd Euron. They've really got to get bad motherfukkers to play those two, man. If it wasn't so similar of a role, I'd fukking love to see Rollo from Vikings play Victarion.exactly, but i doubt they'll want to cuz
1. that shyt will get EXTREMELY boring to watch on tv, added to how boring King's Landing gets when Tywin dies they're gonna have to cut some shyt out to make sure people still tune in to see their favorite characters
2. Everyone elses storyline would prolly already be on the cusp of 6th book material outside of Jon (pretty sure they're gonna speed things up a little bit at the wall so it ends with him gettin stabbed up)
They're gonna have to be finished with book 5 Dany material by next season and find someway to make that shyt interesting, but i just dont see how
They're gonna show Balon's brothers, right? They wouldn't skip them, dude, RIGHT?
