Sword boy: Ser Barristan v Sons of the Harpy

It's not the most beautifully choreographed fight in the whole thing, and takes place in a dark and anonymous alleyway, crowded with slavery-loving arseholes.

But there is something unspeakably noble in Ser Barristan Selmy, a rare man of true honour, dying to save a bunch of dickless ex-slaves on the far side of the world, wading into a fight he can never win - not because he wants t o impress anybody or show off how cool he is - but because it's the right fucking thing to do

Most of the knights in the series are complete dicks - it's notable that some of the most truly honourable fighters do not have that kind of title -but Ser Barristan stays true to his vows and lays down his life for Grey Worm, because honour demands it.
