I really hate necroposting, but after Dereich and X brought it up I just had to.
Congratulations, lads! We predicted the constitutional Westeros ending - via Deus Ex Machina - five years ago!
We did that with a few things. Arya killing the Night's King, Stannis getting killed by Ramsay was posted literally either a day before or the day of the episode where he loses the Battle of Winterfell and then gets killed (albeit by Brienne), Benjen dying at the Others' hands in a sacrifice that accomplished absolutely nothing, Theon being killed by the Night's King in the final battle in a last act of courage shortly before Arya kills the NK, etc.
