5 Characters Who Could Kill Ramsay Bolton In Game Of Thrones Season 6
5. Brienne Of Tarth
Brienne was tasked all the way back in season two with finding the Stark girls (Sansa & Arya) before Cersei could get her hands on them.
It is established at the end of season five that Brienne knows where Sansa is, and could now potentially find her in the Northern wilderness. Since both Sansa and Theon survived the jump from Winterfell's walls, imaginably in hot pursuit of them both would be Ramsay, after all Sansa is now seen as the key to the North with her brothers and father gone.
Somewhere in the forest, as Ramsay searches relentlessly for Sansa, there could be a meeting between Brienne and the b*stard Bolton. Facing facts Brienne is a highly skilled warrior, having already killed the Hound, and one would imagine she would kill Ramsay without much of a fight. The only issue with that outcome is the question what next for all involved.
Having Brienne kill Ramsay adds little to the development of her character or Sansas. If Ramsay was to die by Brienne's sword then where does she take Sansa, as the only place realistically now for Sansa to go is back to a Bolton controlled Winterfell.
Brienne on the other hand has to choose between just letting Sansa to go back to Winterfell, or taking her on the journey to find Arya; ignoring the fact, that it took Sansa three and a half seasons just to get back to Winterfell in the first place.
Actual Likelihood: This idea is really dependent on Brienne being able to find Sansa's trail in the midst of a recently ended battle, the likelihood of this happening is probably slim. Really the one to kill Ramsay should have more to do with him than just a first meeting fight, and the writers know that.
