Last week's episode of extremely popular HBO show "Game of Thrones" still has fans talking. The Purple Wedding saw the gruesome death to the much hated King Joffrey. There are many cliffhangers left unanswered.

Audiences are hoping to have their questions answered this week. Who killed King Joffrey? There are many suspects including his own mother. And who will take over King Joffrey's rule? His mother is an option, but does that change as she is a suspect in his murder?

Many suspect Tyrion of the king's murder, but it seems to even a casual fan that he is being set up.

Anyone could be a suspect, from Dany to Stannis to Mance Rayder.

Many people had motives for wanting Joffrey dead.

Whoever killed Joffrey, there is no doubt, the search will consume most of Sunday's episode.

Many fans are on the edge of their seats waiting to see what will happen next. And HBO has provided some solace in the form of a preview.
