Gotta say this was a pretty awesome episode. From the start we have Ice being destroyed for Oathkeeper and Widows Wail (only cunts name their swords hehehe). Not important but pretty cool to hear the Stark theme fade into Rains of Castamere during the scene. Then Jaimes's redemption arc continues as he tells his father to shove it and gets his famous golden hand. Also a reference to Dunk during the scene with the white book, four pages baby! We get to see some Oberyn already being a badass and then straight up confirming that Rhaegar left Elia for another women!!! To finish off the KL section we have Tyrion and Sansa playing their scenes perfectly, as usual. Then the re-introduction of Ser Dontos and his gift of the hairnet (Now necklace).
Away from KL we have Jon Snow who's acting has gotten 200% better from last season. Would've liked to see more scenes from him but if he keeps it up he'll be able to carry his character which he has pretty much failed to do the first 3 seasons. We also have Dany's arc prepare to be yawning all season...I don't have much to comment on but I'm not a big fan of the recast of Daario Naharis he isn't sleezy enough. Finally of course we have the battle at the Inn of the Crossroads. Aryas character in the show seems to have some of the best interactions e.g Tywin at Harrenhal and now the Hound. Their banter was clever and amusing and they played off each other well.

The final scene with Arya killing Poliver was well done and a throwback to the recently released TWOW chapter.
“You’ll need to carry me.”
See? thought Mercy. You know your line, and so do I.
“Think so?” asked Arya, sweetly.
Raff the Sweetling looked up sharply as the long thin blade came sliding from her sleeve. She slipped it through his throat beneath the chin, twisted, and ripped it back out sideways with a single smooth slash. A fine red rain followed, and in his eyes the light went out.
The dialogue wasn't the same but close enough and they left a nice callback to how she mocked the tickler, a kind of mesh between the two scenes and very well done. I still would have preferred her to lose it like she did on the tickler but this scene was great as well.
And as a Brienne-lover and BriennexJaime shipper, I loved that part too. Not to mention Cersei and Oberyn's sass. :3
Maybe George did it on purpose, because the books are meant to discourage revenge. It counts for Joffrey's death too. The aftermath will be terrible for all parts, and despite everything he was just a little kid.
