Spoiler for Garlemald...
The scene in Garlemald where the Legatus solemnly laments over the passing of an age, of all he knew. His nation, the respect and dignity they once had, and rather and face a world where bitter enemies become allies, rather than sacrifice his pride, he takes the easy way out and takes a bullet the the head. The errie calm music playing in the background, the blood splattered on the flag remaining as a constant reminder, a symol of a fallen nation. It was masterful, bravo to the writers for this
Of the many great moments in Endwalker, this was one of the most powerful.
