Ramsay Bolton (formerly Snow) is a major character in the fourth and fifth seasons. He initially appeared as a recurring character in the third season. He is portrayed by Iwan Rheon, and debuts in "Dark Wings, Dark Words". He was first referred to in Season 2, but his actual name is not mentioned until "Mhysa". As the bastard son of Lord Roose Bolton, Ramsay originally used the traditional surname for bastards born in the North, and was known as "Ramsay Snow". However, he has recently been legitimized as Lord Roose's lawful son, and has therefore been officially renamed "Ramsay Bolton" and thus giving him all the rights of a trueborn son. Ramsay is violent and sadistic, and fond of the ancient Bolton practice of flaying. During the War of the Five Kings, he is initially an ally of Robb Stark when he is dispatched by his father to retake Winterfell from Theon Greyjoy. Ramsay, however, massacres the ironborn garrison, puts the castle to the torch, and takes Theon prisoner, all part of his father's plan to betray Robb and the Northern army to the Lannisters. He subjects Theon to extensive physical and psychological torture, turning him into a broken pet named "Reek".
