Re: SPOILER *all five books* THREAD FOR Game of Thrones (TV series discussion)
It's almost guranteed that Epilogue/Prologue characters die.
As for Winds of Winter's prologue. I'm putting my money on Balon Swann hunting down Darkstar, only to meet his end, whilst Darkstar reveals some pretty awesome secrets to us. A nice epilogue for Winds for me, would be a flashback of when Ned spent the his final hours in the Black Cells, thinking over everything that's happened and revealing a lot of the series most discussed secrets.
