One thing we learned in the season premiere of Game of Thrones Season 4 is that Oberyn Martell (Pedro Pascal) hates the Hound’s brother, the Mountain, because the Mountain raped and killed his sister (which is a pretty good reason to hate somebody). So will Oberyn get a chance to get some revenge on the Mountain this season? It sure looks like it.

In several of the trailers leading up to Season 4, we saw shots of Oberyn whirling and twirling with a spear while fighting a monstrous man in full armor holding a greatsword. Our money says that giant is the Mountain, since the only other character who’s that big is Hodor and we seriously doubt he suddenly became a knight (although, how cool would Ser Hodor be?!).

Further evidence for these two butting heads comes from the episode titles themselves. Episode 8 is titled, “The Mountain and the Viper”, which seems like a pretty good indication that these two will be facing off in the episode. If that’s the case, the Mountain had better watch out because, according to Oberyn, “The Lannisters aren’t the only ones who pay their debts.” Chills.

“The Mountain and the Viper” airs June 1 on HBO.
