At least, idle commentary that might allow you to extrapolate enough to constitute spoilers.
First, I actually went back to HBO Go to see what the episode title was and am astounded that it is listed as Game of Thrones 70. I’d been referring to it as Battle of Winterfell leading up to the episode, because, well, that was what it was expected to be and what it was. It’s almost as if the actual title was supposed to be inserted where a placeholder had been, and someone forgot.
Next, if you watched it you can guess at what key moment I yelled out “YES!” loudly enough to be heard through the wall and closed door from the other room. Not what I had expected, but not something surprising either.
After last week’s episode when Bran made himself sound like Rand Al’Thor and the Night King sound like the Dark One from Wheel of Time, I wondered if there would be some degree of virtual jousting between them as if the Godswood at Winterfell was Shayol Ghul and this was Tarmon Gaidon.
I feel like I need to rewatch to be sure I caught who did or didn’t survive more accurately, but I will probably see that information detailed soon enough by YouTubers. There were three super appropriately heroic deaths that were clear, and another that was both heroic and explained a lot. Or raised questions.
I really can’t say much without outright discussing it. It threw a ton of theories and deeper stuff out the window, overall. Maybe not for how the books will do things when they select someone to finish them in a decade or two after Martin has pulled a Jordan but less untimely and with slower writing.
I haven’t checked HBO again, but others seem to be referencing an episode name of The Long Night. That would make sense as a name, since it was essentially all over the course of one night.
