Was talking to a coworker trying to figure out a list of things the show has basically confirmed
Jon Snow lives/is resurrected - pretty obvious it would happen, but still confirmed it
Ramsay wrote the Pink Letter - I think last ep seals it wasn't Stannis/Mance/etc.
Dany takes over Kahl Jhaqo's khalasar and probably others - writing was on the wall and the show confirmed it
Tyrion becomes Dany's top advisor/likely Hand of the Queen - basically confirmed last season. Tyrion in Meereen is more or less Tyrion in King's Landing circa season 2
*edit*
Ramsay takes out Roose - clear one of them was taking out the other at some point
Euron was responsible for Balon's death - very obvious, but straight showed it
They're also telegraphing this Hound/Mountain fight pretty hard. Not even bothering calling Ser Robert Strong by the fake name and just straight acknowledging him as reanimated Gregor. The Waif in the House of Black & White asking Arya what happened to the Hound.... doubt that was a throwaway line. Mountain vs. Hound ep 8, 9 or 10 I'll bet ten stacks of Coli Cash
If Troll R.R. Martin is never going to finish the books at least we're getting answers in some fashion
