Things come to a head for Daenerys, Stannis and Jon Snow in the new look at the HBO hit.
"Game of Thrones"

HBO has unveiled its third trailer for Game of Thrones season four -- and it's full of pithy lines from the show's major players.

Among the gems:

"Always keep your foes confused. If they don't know who you are, or what you want, they can't know what you plan to do next." - Petyr

"I will answer injustice with justice." - Daenerys

"I will not become a page in someone else's history book." - Stannis

There's also some self-doubt from Jon Snow -- who proclaims he's "done plenty wrong" -- and signs that things are getting even worse for Sansa (and we thought that wasn't possible). The crown jewel of the piece is a shot of Tywin sitting on the Iron Throne, looking quite regal.

Game of Thrones season four debuts Sunday, April 6, at 9 p.m. on HBO.
