Too many to list but I’ll give it a go:
Joffrey’S death
The viper and the mountain fight - it’s just so we’ll done
Cersei burning shit down
Tommen just stepping out of the window- it was so wonderfully underplayed so you almost didn’t realise what had happened
The “every fucking chicken scene” and anytime the hound says “cunt” I don’t know why, I don’t love that word but I actually fancy him more when he says it
When Arya jumps off the horse to pretend to be looking for food and warmth when she hears Lannister soldiers laughing about what they did at the red wedding, stabs one of them and the hound has to jump in. Afterwards he says irritably “next time can you tell me when you’re going to do something like that” there’s something so parental almost in the way he says it
When the hound tells Brienne nowhere is safe and if she doesn’t realise that then she’s not to the one to watch over Arya
Hard Home - the whole episode. Gives me goosebumps every time
Jon punching Ramsey
Arya and Sansa teaming up to take little finger out
danaerys when she launches the broken slave collars at the city walls
Anything with Bron
Jamie and Brienne’s goodbye where he gives her the sword and armour. Then the scene where they meet again on opposite sides of the fight, and their silent goodbye as Jamie sees Brienne sail off in the boat
Tyrion at the Eyrie
Syrio Forrell’s brave last scene fighting with a wooden sword “what do we say to death boy? Not today”
Everything with Olenna “you didn’t think I’d have let you marry that monster did you?”
And tell Cersei I want her to know it was me
“He’s a sword swallower through and through”
So many I don’t think I’ve even scratched the surface there
