The love for the "Scouring of the Shire" is interesting. It leaves a lot open for what GRRM can do with the end of the series, within that scope. Whoever remains standing in the end to claim the throne, victorious, could return to King's Landing (or Dragonstone, or Winterfell, wherever their chosen seat may be), to find that there is already an open rebellion from remaining lords. The series ends with a hero continuing to fight the good fight, after having defeated the "big" enemies (Cersei and the Night's King?)
Or, the "big" fights end, only for our Hero to return home to find nothing to rule over.
Reading through wikis after some of these convos, I found some other interesting tidbits:
The three "Great" Targ dragons only took the field of battle together once or twice... will we see the same MO from Dany? Tyrion reads a lot, so I could see him advising her to keep them in a rotation of sorts based on history, or something along those lines. It ensures that at least one of her dragons will always be safe; it opens the path for a big story moment where someone shows up with second/third dragons to save the day in a battle where only one/two were present; it saves HBO a bunch of CGI money. It will be interesting to see if they address that in the writing/plot, or if it's just kind of ignored and she uses all three of her dragons at will.
The other thing to consider in the end game: It's pretty much confirmed that the Maesters conspired to suppress magic, which went hand-in-hand with the decline of the dragons.
Now that Dragons are back, and the Night's King is active, are the Maesters going to act to once again suppress magic? Or do they just ignore the realm's issues and let them play out, planning to clean up the mess of whoever/whatever remains in the end? Is that why Sam's pleadings are being ignored, even though the Maesters know he is likely telling the truth about everything, and that they likely know dragons have returned?
