What happened to Ramsay Bolton?

the North to fight this out “the old way” and Ramsay demurred. But that was before Ramsay set Rickon free just so he could shoot the boy through the heart with an arrow right in front of Jon.

When the battle finally got going, Jon was in the thick of it, risking his life, while Ramsay watched from afar. It seemed for a moment like that strategy might work. Once the Knights of the Vale showed up, Ramsay had a head start back to Winterfell, where he could have hidden for a long while, if Snow didn’t have a Giant in his army to decimate the door.

Ramsay made a few futile attempts to shoot Snow with an arrow. Lord Bolton probably should have caught Snow off-guard rather than wasting his ammo on a dying Wun Wun. Instead, Snow charged Ramsay, knocked him down, then pummelled him. Snow could have killed Ramsay. But then he looked up and saw Sansa, and he thought either (a) he shouldn’t do this in front of a lady or (b) this lady should really be the one to do this.

It was glorious to see Snow get a few punches in. It was just as magnificent to see Ramsay incapacitated.

● Sansa got to have the final word …

This is Sansa’s season. After viewers have watched Ned Stark’s daughter suffer one indignity after another, it was only right that she got some agency. She’s proved herself to be strategically adept, saving the day by summoning Littlefinger and his friends.

When the time came, she chose to bid adieu to her rapist husband. She went to visit him in the dungeon where he was being held, tied and powerless. And – from the looks of it – she even got to choose the way he would die.

● ... but she didn’t have to get her hands dirty

What does it say about this show that it makes a watcher pine to see a young lady plunge a sword through a man’s heart? That would have been a good way for Sansa to kill Ramsay.

But there was something even more gratifying about seeing her set his death in motion without having to lift a finger. Instead she walked away while the dogs did the dirty work. ● It was grotesque. Ramsay had done countless terrible things to too many innocent people. It seemed right for him to go out in a grisly way. And while the show didn’t explicitly show everything, the moment where one of his dogs bit into his face was plenty to get the point across.

● He was undone by his own monstrosity

Sansa turned Ramsay’s own dogs against him. To the end, he didn’t think they would disobey him. After all, he was their master. – Washington Post
