Ι enjoyed Arianne as a character but i loved plot of Young Griff.It's such a game changer and even if he is not the real deal(i prefer him to be fake)i love his plot and propably brings Blackfyre back in the game.Also,i hope they won't cut Kingsmoot and Theon's uncles.Victarion and Euron are some of my favorites post-Storm of Swords characters.Especially the mysterious Euron.
