[series]Well, 'zombies' have been in the series from the first chapter of book one. If Beric/Cat has a connection to the wights, I could buy it
I actually never thought about that. Maybe I will come to peace with it. So far, this is one of the only things in ASOIAF that really bothers me. Right now it's just one chapter, I will have to see how it all works out..
(Huge ASOS) I'm still reading AFFC so I'm only speaking fromthe epilogue, but UnCat wasn't even out of the realm of possibilities and, although it comes as a shocking reveal, the book establishes more than once that zombie shit is happening all the time with Beric. He dies and is brought back to life several times. Cat only looks like a zombie because they screwed with her so much in the Red Wedding. It's not out of nowhere and in the overall scheme of things it's definitely less "dumb" than the shadow assassin, because from the very first chapter the series tells you there's undead stuff at play in this world.
I just always thought it was kind of exclusive to Beric. But as I said, I already didn't like it during the brotherhood-storyline. But I don't want to be too fast to judge. I'm waiting for a positive surprise!
