Of course she dies. This is Game of Thrones. All men [and women] must die.
I mean, look at Beric Dondarrion. He’s died about 7 times!
Still, I find it amazing that people can talk/theorize/speculate about the TV series as if the books, which are being followed very closely, did not exist. I have friends who are complaining about Joffrey and hope that he dies (instead of all the other kids), who think Tywin is a complete jerk who should get his comeuppance, and who hope Sansa is able to escape King’s Landing. And then complain that the show is too slow and that they can’t wait! It’s like, “do you really want to talk about A Song of Ice And Fire?” It’s clear from the comments here that no, people actually don’t.
