If you're going to discuss the previews for the next episode, please use spoiler tags. If an event has been shown as going to happen (promotional scene or photo/news discussion in the media) then this information needs to be in spoiler tags too. You can speculate freely on future episodes as long as it's not based on the known via shown images or reliable news sources. Remember, if you want to talk about what may happen without having to use spoilers, just go to the corresponding episode's thread and chat away.
Moderators Note- HBO is not releasing their usual synopsis for episodes nine and ten of season six for Game of Thrones.
ETA I did find some description for this episode, according to EW, “Battle of the Bastards” (David Benioff and Dan Weiss). The submission even includes a cryptic description: “Terms of surrender are rejected and accepted.”
As the Starks prepare to fight, Davos loses something dear. Ramsay plays a game. Daenerys faces a choice.
Yeah I saw conflicting reports on whether there is a synposis or not. According to Entertainment Weekly there wasn't going to be any. And then other sites had other synposis such as on Watchers on The WALL has one and then IMDB has another. It's strange. I looked on HBO and there wasn't any synposis.
