George R.R. Martin says the ending for his 'A Song of Ice and Fire' series will be 'significantly different' from ‘Game of Thrones' “[The book’s ending is] going to be significantly different. Some characters who are alive in my book are going to be dead in the show, and vice versa" Many details remain uncertain: “I was going to kill more people. Not the ones they killed [in the show]. They made it more of a happy ending. I don’t see a happy ending for Tyrion. His whole arc has been tragic from the first. I was going to have Sansa die, but she’s been so appealing in the show... maybe I’ll let her live" (via @THR)
