I'm thinking Luwin will still die but maybe not when we expect him too and the reeds will come in later, maybe not until season three, I'm hoping so anyways, keeping my fingers crossed, i like the reeds, i would be upset if they don't cast them.
I am so disappointed they didn't allow Arya to kill the tickler, I hope they make up for this. That was by far one of the best parts in Storm of swords and they just took it away. With that said, i'm still loving GoT. I hope they at least show her dreams when she wargs into Nymeria.
