To really understand what's happening on "Game of Thrones," it's necessary to rewatch. You'll re-learn a lot of things you may have forgotten, like why Arya and Sansa's relationship is strained, and you'll also learn completely new things, like how Daenerys is connected to all this in the first place. There's a lot of family trees and names and places in this show, so for the most effective "Game of Thrones" rewatch, turn on the captions.
