The end result: Ned was executed for treason, fanning the flames of aforementioned tension, which grew into a spectacularly bloody, continent-wide civil war, leaving thousands dead, the land ravaged and the economy hanging on by a thread just before the start of a winter that could last for generations!]] All of this, just because Petyr DidntGetTheGirl! The guy takes {{Yandere}} to a [[UpToEleven whole new level of insanity.]]
