One quick thought, and one question:
1) LSH killing Freys wouldn't make good television at this point, because we don't know a single Frey aside from Walder Frey. There'd have to be a lot of exposition - like "hey we're the Freys, remember when we killed Robb 2 years ago? That was crazy. Let's all go for a walk," followed by them being captured and lynched, and then some exposition about how the hell Catelyn Stark is still somewhat-alive - if anyone can even recognize her at that point.
The Riverlands is so far out of the average viewer's mind right now.
2) A question for you all - do you think GRRM has a plan? I mean, obviously he must know some of the main points (Jon's parentage, who will win in the end), but how much do you think he knows about how he wants all these stories to wrap up?
The reason I ask is because nearly everything this season has been a modified or tidied-up version of what we got in the books. In comparison to the show (which obviously isn't perfect), I feel like the books may have spiraled out of control a bit. Or perhaps, in light of what the show has kept, we're seeing some ideas that have been introduced in the book that may amount to a lot of worthless pages in the end.
Let's put it this way: we're 5 books in with 2 to go. We have a Stannis / Bolton battle about to happen, there's drama at the Wall, Bran is a tree, Arya still hasn't amounted to much, Aegon is invading, Daenerys is in the middle of nowhere, Mereen is besieged, Cersei and Margaery are in captivity to the church, Littlefinger and Sansa are sitting around. Also, Lady Stoneheart, Jaime and Brienne, Samwell Tarly, the Ironborn, the Martells, Coldhands, the Others, Dragons, Jorah and Tyrion, Tower of Joy, prophecies.
How confident are you, with two books left, that these stories will wrap up in a satisfying way?
Personally, I feel like the show will do a better job of that because they've trimmed a lot of fat. I'd like to think that GRRM has a plan for it all, but I'm not sure. Perhaps if he did, the books wouldn't have gone from a trilogy, to 5, to 7. But that's just my two cents.
