The Quote: "Go on, do your duty." Stannis Baratheon went through a pretty crazy trajectory throughout the series. We were worried about him, then were bored with him, then cheered for him, then sympathized with him, and finally outright hated him. When he made his hasty march on Winterfell to root out the Boltons, he seemed to just be going through the motions. His final charge into battle was less epic and more "Okay, let's get this over with." Still, being the badass that he is, he was one of the few survivors when the battle was done. But he was pretty defenseless when Brienne of Tarth stumbles upon him seeking revenge for her beloved Renly. When Brienne unsheathes her sword, Stannis doesn't beg, curse or protest. He tells her to "do your duty". In the end, that's what really mattered to Stannis: honor and duty. Initially, he only sought the Iron Throne because by law it was his right, but along the way Melissandre's prophecies got into his head and made him believe he was meant to be a savior. As a result, he did some terrible things - dishonorable things. Having lost everything, all Stannis has left is his sense of honor, and in this moment the honorable thing is to die for his sins.
