Event: Lyanna Mormont - Convincing Argument (Political Wins)

Episode 10: The Winds of Winter at 58:33
58:33 (+3) Lyanna Mormont:
As the Knights of the Vale and Northerners bicker about their next plans and returning home, Lyanna calls out the other Northern lords and rallies them behind Jon Snow.

"Your son was butchered at the Red Wedding, Lord Manderly, but you refused the call. You swore allegiance to House Stark, Lord Glover, but in their hour of greatest need, you refused the call. And you, Lord Cerwyn, your father was skinned alive by Ramsay Bolton. Still you refused the call. But House Mormont remembers. The North remembers. We know no king but the King in the North, whose name is Stark. I don't care if he's a bastard. Ned Stark's blood runs through his veins. He's my king from this day until his last day."
