"Game of Thrones" season 4, episode 6 spoilers will revolve around the trial of Tyrion who didn't make an appearance in last episode. Since the odds are stacked up against him, will Cersei succeed in finally getting rid of her brother?

In the official "Game of Thrones" season 4, episode 6 spoilers released by HBO, Yara Greyjoy will get a chance to fulfill her promise to rescue Theon Greyjoy from the clutches of the sadistic Ramsay Snow.

Stannis Baratheon also reiterates his claim to the Iron Throne by virtue of his blood, being the younger brother and probably rightful heir of Robert Baratheon.

But what will dominate "Game of Thrones" season 4, episode 6 is the trial of Tyrion in a kangaroo court. His guilt on the death of Joffrey Baratheon is but preordained. But it's not that easy to kill the brainiest of the Lannister children.

Tyrion has been in the same situation when he was tried at the Eyrie. That time, he chose trial by combat, and Bronn came to his aid to kill Ser Vardes Egen and eventually win Tyrion's freedom.

With all the odds stacked against him-with Cersei working behind the scenes and his father Tywin (sitting as a head judge) virtually demanding that he confesses-will Tyrion ask for a trial by combat this time?

Warning, "Game of Thrones" season 4, episode 6 spoilers up ahead:

While the HBO preview didn't offer much, George R. R. Martin's book, "Song of Fire and Ice," does provide answers to what happens next. And if the show will not veer away from the book, somebody will come forward to be Tyrion's champion in the trial by combat against The Mountain. Hint: it's not going to be Bronn.

Somebody unexpected will come forward to be Tyrion's champion and it's going to be Prince Oberyn Martell, who has plenty of axe to grind against Gregor "The Mountain" Clane whom he blamed for the death of his sister and her children.

"Game of Thrones" season 6, episode 4 will air on HBO on Sunday.
