Deliberate mistake: During the "previously on Game of Thrones" snippets, before the opening credits sequence, there are two flipped shots of Sansa and Jaime as she tells him that she has always wanted to be there for Cersei's execution, but she won't get the chance. (00:01:45)

Game of Thrones (2011)
1 deliberate mistake in season 8 - chronological order
Starring: Lena Headey, Peter Dinklage, Emilia Clarke, Maisie Williams, Michelle Fairley
The Last Of The Starks - S8-E4
Character mistake: Gendry gets declared as Lord Gendry Baratheon of Storm's End by Daenerys. But he refers to himself as Gendry Rivers - the surname given to bastards from the Riverlands. Gendry comes from King's Landing, and bastards from there are called Waters, not Rivers. Given that Gendry is not an acknowledged highborn bastard, he should never have had a surname in the first place.
Cripples, Bastards, and Broken Things - S1-E4
Daenerys Targaryen: If you ever lay a hand on me again, it'll be the last time you have hands.
Trivia: Cersei remarks to Tyrion that she had heard his nose was cut off during the Battle of Blackwater Bay. This is a reference to the books, in which part of Tyrion's nose was indeed cut off.
Question: Is there any place in the books, movies, or directly from George R.R. Martin to say why the Game of Thrones world has such unpredictable seasons? Magical, Scientific, Alchemical (ie in-between).





Chosen answer: Well Magic does come to mind. The White Walkers bring with them the winter. Because of this, the seasons are very unpredictable. "Winter Is Coming" refers to this.
