Episode 3 - "What Is Dead May Never Die"
Catelyn Stark arrives at King Renly's camp to negotiate an alliance. Tyrion also tries to gain supports for Joffrey's cause by proposing three different marriages. At Winterfell, Bran Stark needs help to decipher his dreams.
Episode 4 - "Garden of Bones"
Catelyn tries to convince the Baratheon brothers to abandon their quarrel and unite against the Lannisters (a memorable scene from the book, which briljantly shows how stubborn the two kings are), while Sansa is chastised by Joffrey in revenge for her brother's victories (and nudity follows). Arya and Gendry are taken captives to the castle of Harrenhal (I wonder if they skip Arya's fight at a settlement, and the atrocities commited by The Mountain's men). After her exhausting journey through the desert, Daenerys arrives at the gates of the prosperous city of Qarth. (Yep, they skip the City of Bones. Yet the title of the episode still seems to make reference to it.)
Episode 5 - "The Ghost of Harrenhal"
In Harrenhal, Arya Stark is promised help by the mysterious Jaqen H’ghar, one of the three caged prisoners during her trip to the Wall. The new situation at Renly's camp forces Catelyn to flee (Awww, we have to wait till episode 5 for this to happen? Or do they perhaps show it at the end of episode 4?). Theon sails from Pyke prepared to prove that he is a true Ironborn. The Night's Watch arrive at an ancient fortress called the Fist of the First Men, where they intend to make a stand.
Episode 6 - "The Old Gods and the New"
Somewhere in this season they will have to show the most notorious and creepy scene with Melisandre from the book.
Episode 7 - "A Man Without Honor"
Probably focusses on the adventures of Brienne and Jaime.
Episode 8 - "The Prince of Winterfell"
This could be referring to the attack on Winterfell.
Episode 9 - "Blackwater"
It is rumoured that George R. R. Martin co-directed this episode. The title of this episode is probably referring to the most epic battle in the entire book. This is probably where most of the budget of the season went.
Episode 10 - "Valar Morghulis"
This is probably the episode where Arya escapes Harrenhal. This will be epic as well, and will require some visual effects for Jaqen H’ghar's transformation.
