From that point on, everyone gets 10 inch thick plot armour, and then the last two episodes skip a whole season or two of character development to try and box the show off quickly.
It's the way stuff is done, the characters' changed behavior, incomprehensible logic, stupid explanations, etc.
Television writers pussying out in their finales is its own meme at this point. Makes me respect David Chase and how The Sopranos ended all that much more.
Martin has claimed he flew to HBO to convince them to do 10 seasons of 10 episodes instead of the 8 seasons with just 8 episodes in the final one [1]. It was straight up just D.B. Weiss and David Benioff call how the series ended.

You know there are two more episodes, right? That seems like an obvious finale reveal.
They just invent stuff that they have no idea how to explain later. Just like Lost.
There are also stupid leaps of faith like Holly's mom hobbling out of bed and sticking an oxygen tank in a clothes dryer(as if that would even do anything)...
