No, i mean the season 4 finale, the one that aired this past Sunday.

I got some things spoiled for me simply because the showrunners decided to remove/change a bunch of "important stuff" that apparently was in the books, and as a result of them not showing those things, all the book-readers went nuts and on damn near every site i went to there were people talking about/comparing what in the episode was removed/changed from the same scenes in the books...

I haven't read any of the books, but i assume you have since you posted that spoiler warning? (unless someone had already spoiled that thing for you, and that's how you knew it?)
