Discussion questions if anyone wants to share an opinion:
I know the NK's endgame has been brought up numerous times, but it really plays into his next move. Is the army of the dead going to head towards Winterfell and then follow the King's Road to Kings Landing ignoring everything else? Will they go after Castle Black? Will they just meander all around the north, attacking each house as they encounter it before going south? Is there a true destination or just a spread and conquer mentality? It's not like they should have any real idea of the lay of the land at all. Will they bother with Bear Island or Pyke?
I don't see them splitting up their forces since the ice dragon is their war hammer and numbers are their strength.
What is the most defensible location for the living to make a stand? The combination of the Bloody Gate and the Eyrie has to be right up there, I'd think. Riverrun's ability to redirect water is an intriguing option, but I feel like the ice dragon just freezes it and nullifies the advantage.
Will Jaime or Tyrion think about using wildfire as a weapon? If you laid a trap, that stuff can wipe out huge chunks of wights quickly before the NK could extinguish the flames.
Can a dragonglass arrow take down Viserion, or does it need to be something more significant? From what I've seen, it doesn't take a huge amount of contact with dragonglass to end a wight walker. It seems like a hail of dragonglass arrows would be a pretty formidable weapon against the NK's dragon. I'm assuming weapons have been made since the mining of Dragon Stone was taking place several episodes ago.
Does Bronn go with Jaime? He didn't witness the wight during the meeting. He says he's loyal to himself and gold, but he's definitely formed a bond with Mr. Golden Hand.
Do any dragons exist at the end of the series? I have a feeling none survive, but that's just a guess based on nothing but opinion.
