Game of Thrones Season 4 Spoilers: The Mountain and The Viper Fight Preview

Game of Thrones newest episode this Sunday will depict the showdown between Oberyn, aka The Red Viper, and The Mountain to decide Tyrion Lannister's fate in a trial by combat.

Oberyn has no love for the Lannisters, but Tyrion has always been cut from a different cloth than the rest of his family. But why is the Red Viper, who earned that moniker from his previous fights, helping the imp?

"It's not hard for Oberyn to recognize that Tyrion is the smartest man in the room," Pascal said, according to TV.com. "Oberyn is not a fan of the Lannisters, so it's not very hard for him to see through the trial and recognize what's really going on. And while he has his own agenda, because he wants nothing but to face the Mountain himself and kill him, to be able to do that on behalf of Tyrion is an extra 'f*ck you' to the Lannisters because he recognizes their hypocrisy and their corruption."

He goes on to explain that Oberyn and Tyrion are not quite friends, but they do have a connection.

"I think there is a little bit of a kindred spirit between the two of them," Pascal said. "Oberyn can recognize that Tyrion is a survivor, and that's through cunning and intelligence. Also, the two of them can relate to the fact that they love to have good times! If they could stay alive together, I bet they'll be really great pals."
