i'm not touching them with a ten-foot pole bc i'm a book reader too and apparently there are book spoilers from TWOW in there too..

basically someone on 4chan put up 4-5 screenshots of scenes that contain key spoilers, claiming they come from a leaked copy of episode 10.

but episode 10 is nowhere to be found online. speculation is that the screenshots come from the "Inside The Episode" features that air after the show does. those often get sent out to journalists early, so they have some material to work off as they watch the episode for reviews.

this link has more info on the "leak", and the bottom of the page has the screenshots which i have not looked at, because there's a big warning before them that it will spoil not just the show but also the future books.
