With three remaining episodes before the end of season 4, HBO is slowly wrapping up "Game of Thrones" as the story unfolds in the upcoming episode which will decide Tyrion's fate. Episode 8, "The Mountain and The Viper," features Prince Oberyn Martell as Tyrion's champion when he asked for a trial by combat in "The Laws of Gods and Men."

Accused of murdering the boy king Joffrey, Tyrion is left with no choice but to ask for trial by combat after Shea testifies against him. Since Bronn is out of the picture, The Red Viper steps in as his champion to get the chance to fight against The Mountain (Ser Gregor Clegane), and to avenge the death of his sister.

"I'm your friend, and when have you ever risked your life for me," says Bronn in "Game of Thrones" season 4 after he told Tyrion that he can't be his champion. "I like you ... I just like myself more. I'm sorry it has to be this way." Tyrion, however, doesn't get angry and they say farewell to one another.

Based on the previous episode, Oberyn revealed that Cersei's champion is the man who raped and killed his sister. The Mountain and the Red Viper's fight is going to be the spotlight for the show's episode 8 based on the 36-second promo of the show, written by David Benioff and D.B. Weiss, the Sunday's night episode will be directed by Alex Graves.
