The new trailer for "Game of Thrones" Season 4 has been released. The trailer is nicknamed Vengeance and features a series of characters speaking about justice and avenging the deaths of lost loved ones. What are the clues we can gather about the story-lines in Season 4? And who will be going after who?

The trailer begins with Arya Stark relaying a list of characters she harbors a death vendetta against. We already know she harbors a grudge against Cercei and Geoffrey Lanister, but she's now added the names of Tywin, Cercei's father, and the "Red Woman" otherwise known as Melisandre. How does her new companion, the Hound, relate to her quest to annihilate his former masters?

We know all of the Stark family is seeking revenge for the brutal scourge of their bloodline acted out in the last three seasons. So few remain, and it seems unlikely there will be any justice for their family's plight. Sansa speaks to Tyrion about being haunted by her family's death. Jon Snow expresses some desire for justice, although it's not made clear whether it will be against the murderers of Robb Stark or attempted mutineers in the army of Mormont.

Daenarys Targeres still wants justice for the great outrage of her family members exile after their father was dethroned. As she is of the original bloodline that sat on the iron throne, she is thirstily building a more and more impressive army to take over Westeros. Appatrently, she also has a jumbo-sized dragon now. But besides all that, there is a clip where a man talks to her about repaying injustice with mercy, intercut with scenes of the siege of a city. What is the specific injustice they are talking about?

The Red Viper is a new character in this season and makes appearance here alongside Cercei. He himself talks about vengeance to her. He is also seen fighting in an arena. It appears that he has aligned himself with the Lannisters fully. But what are his motives and what does he hope to achieve? Fans of the book say that it will be hard to know what the reasons behind his actions are and what he will wind up doing next.
