To keep up my spectacular wrong predictions so far, I think we'll end episode 10 as follows:
> Stannis starts siege of Winterfell and pushes through. Either during or the night before, Sansa injures Ramsey non-fatally and escapes. Reek will help her in some way. She will be picked up outside by Brienne and be grateful for her help. She will demand to be taken to the wall where her brother is.....
> ....who will be dead. I honestly can't see Jon living. He's become Lord Commander, he's brought down the wildlings from the North. He has no army or interest in the Throne. I think Bran and Dany will be more instrumental in the war of the whitewalkers as well - we're all desperate to know if Mel knows more about his lineage than us, but if it's not true/critical to the plot then there's no point knowing;
> I think the episode will end with a show of strength from Melisandre as well. I think for some reason, we'll see some massive explosive power/fire that will decimate the Boltons forces. Mel is now legit;
> Arya will kill Meryn Trant, but it won't be clean. She will use Needle. Jaqen will be pissed;
> Dany will have a scene re-uniting her dragons. She will return to Meereen and make some sort of speech with an intention of going to Westeros next season;
> The episode is called
, so that means someone confesses. Maybe all of them? I think High Sparrow hinted at creative punishment style judgement for this. I can't see the Tyrell's confessing as it would be both of them which leaves Cersei - Jamie will arrive back in time to see the punishment, whatever it is. It will affect Tommen in some way;
> Littlefinger will have a brief scene, I'm not sure why though;
> I know Bran's not in this season, but maybe a cut to him still in that weird place where something of significance is shown, maybe after Drogon flies or something?
That should pad the episode out nicely. I expect a big death and a lot of loose ends still.
