Hother Umber

Lord Hother "Whoresbane" Umber of Last Hearth is a recurring character in the fifth and sixth seasons. He became Lord of Last Hearth following the death of Greatjon Umber in battle.

Season 5
Hother first appears when he arrives at Winterfell to attend the wedding of Ramsay Bolton to "Arya Stark". He refuses to acknowledge Hosteen Frey, instead talking to Lady Barbrey Dustin. During the feast he realizes that Reek is actually Theon Greyjoy, and advises Roose to slit his throat because of his past as a turncloak.

While a blizzard engulfs Winterfell, tensions nearly reach the boiling point. Snowmen resembling Hother are built by squires and soldiers. When Hosteen threatens Lord Wyman Manderly, Hother tries to get him to back but to no avail. Hother rescues Wyman from Hosteen, and their fight is ended by Roose Bolton.

During a meeting between northern lords, Hother explains how he wants to kill Hosteen, and agrees to support Stannis and turn against the Boltons when the time comes.

Season 6
Hother reappears when Ramsay Bolton and Cregan Karstark appear on the Great Hall's balcony announcing that Stannis has been defeated, and that his father has died, meaning he will be the new Warden of the North. Hosteen talks with Lady Dustin, stating that Ramsay probably killed his father. Lady Dustin informs Hother that Stannis has not been defeated.

Hother angrily orders Ramsay to release Lady Dustin after he arrested her for falsely telling him Stannis was defeated.

Hother and the Dustin men take revenge by killing all of Ramsay's hounds and some of his soldiers, stating that the Ghost of Winterfell was behind it. Ramsay deduces they were behind it and punishes them by publicly flaying and executing Lady Dustin. This sparks a riot and Hother kills several Bolton men. When the Bolton guards put the riot down, Ramsay realizes he can't arrest them all with the battle looming, and instead orders Hother and his men to prepare for battle.

At Ramsay's rallying speech two days before the battle, Hother is uninterested and in a symbol of defiance, pisses in the snow in the middle of the speech.

The day before the Battle of Winterfell, Hother follows Ramsay in meeting with Stannis. Afterwards, Stannis states that he doesn't believe Hother will truly fight for Ramsay. At the Battle of Winterfell, Hother leads the Umber and Dustin men, located along Ramsay's flank. Ramsay has sent them to link up with the Karstark force and encircle Stannis. Instead, at the moment they are supposed to outflank Stannis, Hother rallies the northerners and turns on the Boltons, turning the tide of the battle in favor of Stannis. Hother nearly kills Ramsay but the tide of the battle turns him away.

In the following days, when Stannis legitimizes Jon and declares him Jon Stark, Hother joins the rest of the northern lords in kneeling to their new Stark liege.
