Ditto the Plot. (Spoiler Warning!)
Beginning with Season 2, Benioff and Weiss began playing faster and looser with Martin’s account of Westeros than the largely by-the-book Season 1. There were invented subplots, like the awesome, tense relationship between a disguised Arya Stark and Tywin Lannister, as well as the entirely new character of Talisa, Robb Stark’s new bride. It looks like Season 3 will be no different: although Benioff, Weiss, and Martin have been relatively tight-lipped, Martin announced at a panel that “as bloodthirsty as I am in killing characters, David and Dan are killing some characters who are still alive in the books! Their body count is higher than mine.” As for more specific clues about what’s ahead, Entertainment Weekly offered a few in their cover story on the show last month: Jaime is still stuck with Brienne and will go through some major character changes (such as, um, getting “tricked into drinking horse urine”); Arya will move around more and encounter plenty of new faces, not to mention magic; and the love-to-hate-him Joffrey attempts to put the moves on his fiance, Margaery. Sansa will go through an “emotional roller coaster,” including (spoiler alert!) her own wedding. The Starks just can’t catch a break, can they?
