I remember this. I still have the notes on my laptop from a few years ago. I ended up ticking all the ones that made the episode and a cross over the ones that weren't.It wasn't the first episode, it was a video by a leaker, FrikiDoctor, who detailed the general plot if the first episode(s). I think he does subtitles for Spanish Game of Thrones as or something. He did the same thing last season. Last season every single episode was spoiled before they even aired.
