As any fan of Game of Thrones knows, no character is safe. Main characters can die at a moment’s notice, no matter how popular they are amongst fans. So, should we be anxious about the fate of one of Westeros’s more dastardly citizens, The Mountain, in Season 4? The A Song of Ice and Fire book series provides the likely answer.

In case you’ve forgotten, The Mountain is Gregor Clegane, the brother of The Hound. We last saw him in Season 2 at Harrenhal, when he was selecting prisoners from among Arya and her friends to be tortured. He returns in Season 4, being played by newcomer Thor Bjornsson. But now that he’s back, will it only be for a short stay?

The Mountain has been featured less on the show than in the books, where he is a much more rounded-out antagonist, so we’re hoping that Season 4 will fill in more of his story so the audience will send him the proper vitriol he deserves (he truly is a despicable human being, even by GoT-standards). Rapist, baby-killer, brother-disfigurer; The Mountain is a lot of things, and none of them are pleasant. So will his bad deeds catch up to him in Season 4?

As far as we know, The Mountain is returning for one reason and one reason only: To fight. After it looks like Tyrion is going to be found guilty for the murder of King Joffrey, he chooses to have a trial by combat. Tyrion selects new character and Lannister-hater Oberyn Martell to be his champion, while the prosecution, led by Cersei, selects The Mountain. The two engage in an epic battle, with Oberyn mopping the floor with The Mountain for much of the battle until letting his guard down and getting his head smashed in. The Mountain wins the fight, but Oberyn gets the last laugh, as the spear he used was poisoned, and The Mountain suffers a long, painful death.

However, like several deaths in the later books of the series, The Mountain’s death may not be permanent. A mysterious character called Ser Robert Strong shows up in the fifth book in the series, A Dance with Dragons, and bears more than a passing resemblance to the elder Clegane brother. We’re looking forward to see how the show handles this, but in all likelihood The Mountain as we know him is history.
