Game of Thrones season 4 episode 4 will be airing this Sunday, April 27, continuing on from last week's shocking episode.

Last week's Game of Thrones "Breaker of Chains" episode shocked viewers when a "rape" scene between Jaime and his sister Cersei aired. The episode saw Jaime force himself on his sister on an altar as her son Joffrey lay dead just a feet away. After the show aired, author George R.R. Martin said, "The scene was always intended to be disturbing... but I do regret if it has disturbed people for the wrong reasons."

Likely suspects to have killed King Joffrey dwindled down to Margery, Tywin, Tyrion and Oberyn.

The official synopsis for this week's "Oathkeeper" is as follows: "Dany balances justice and mercy. Jaime tasks Brienne with his honor. Jon secures volunteers while Bran, Jojen, Meera and Hodor stumble on shelter."

In a preview promo video for the episode, Cersei is seen challenging Jaime to kill Sansa. Jon Snow also fights for respect at Castle Black.

Game of Thrones Season 4, episode 4 "Oathkeeper", will be airing Sunday, April 27, at 9 p.m. ET on HBO, or alternatively can be watched online through live stream with HBO Go and HBO Connect.
