In Game of Thrones Season 4, Episode 6, the trial on the death of King Joffrey (Jack Gleeson) commences. Tyrion Lannister (Peter Dinklage) is the primary suspect. Cersei (Lena Headey) wants him dead. In the book series, Jaime Lannister helps him escape, after which, Tyrion kills Tywin (Charles Dance).

Oberyn Martell (Pedro Pascal) gets some screentime in the Game of Thrones Season 4, Episode 6 promo video. (Watch the clip on YouTube or scroll down to play the video.) Cersei subtly asks Oberyn to be on her side in Episode 5. This week's new episode reveals Oberyn's own plans in Tyrion's trial.

Here are more Game of Thrones Season 4 spoilers from the GOT 4x6 promo video:

A Daenerys Targaryen Update from Lord Varys

"She has conquered the city and rules as its queen," Lord Varys (Conleth Hill) reports on Daenerys Targaryen's (Emilia Clarke) progress before the Iron Throne and the Council, the GOT 4x6 promo video shows. The same clip features one of Daeny's grownup dragons.

'I'm here for Theon Greyjoy!'

There is a glimmer of hope for Theon Greyjoy (Alfie Allen). His sister Yara (Gemma Whelan) seems to have reached the Dreadfort to rescue Theon from the mad Ramsay Snow (Iwan Rheon). It will be recalled that Ramsay first deceived Theon by introducing himself as one of Yara's servants.

'Do you wish to confess?'

Tywin Lannister asks his son Tywin, "Do you wish to confess?" Tywin's death in GRMM's book series could unfold as is in Game of Thrones Season 4, Episode 6. Jaime Lannister's sympathy for his brother has been obvious in the previous episodes. This bond critically affects the next scenes in the TV adaptation.
