4. The Hound Vs. The Mountain: A Fight To The Death
The hatred between the mighty Cleganes is an escalating friction and one that promises violence. The brothers swords have already met before, but the brevity of it suggests that the purpose of their previous encounters is simply to maximise the hype of a sibling standoff to come. During the fourth season, Gregor The Mountain Clegane was left riddled with poison after his jaw-dropping bout with Oberyn Martell, and Arya left Sandor The Hound Clegane to die alone on the hilltop after his bout with Brienne. However, their deaths are yet to be confirmed, so a clash of these titans may still be on the cards, especially since fan theories have them both still alive. And what a clash it would be.
