With an all new episode of season four of hit HBO historical fantasy drama "Game of Thrones" set to air this Sunday, many fans are on the edge of their seats waiting to see what will happen next.

It seems like the cast and crew have their work cut out for them if they want to top last Sunday's episode.

The new episode will air at 10/9c on Sunday on HBO. The episode will also be available for live stream.

Sunday's episode is entitled "Breaker of Chains," and it comes on the heels of a major change in personnel.

Evil King Joffrey has been killed, but it is unclear who has caused his death.

Many predict that Sunday's episode will provide some answers.

Another question raised by King Joffrey's passing, is who will take over his rule? Could it be young Tommen? Will Cersie Lannister take leadership?

Surely, "Breaker of Chains" will offer some answers come Sunday evening.

The show will air on HBO at 10/9c. Subscribers can also watch the show starting at midnight on HBOGO.com.  And there is a free live stream available here.
