After a brief Memorial Day hiatus, 'Game of Thrones' season 3 will return this Sunday with its penultimate episode of the season "The Rains of Castamere," unnerving both HBO and George R.R. Martin fans alike with the promise of the bloodiest episode yet. The first official photos from Sunday's episode are a bit light on the red, but who's missing from the picture?

'Game of Thrones' fans are already steeling themselves against Sunday's penultimate episode of the season "The Rains of Castamere," which history tells us to be the most intense of the year. HBO's official description of the tightly-covered hour tells us:

Robb presents himself to Walder Frey, and Edmure meets his bride. Jon faces his harshest test yet. Bran discovers a new gift. Daario and Jorah debate how to take Yunkai. House Frey joins with House Tully.

That may not seem like very much to go on, but fans of George R.R. Martin's novels well know that the episode could take a very bloody turn before the final cut to black. Meanwhile, HBO has released the first photos from the hour, of which you may observe that several characters mentioned in the description are nowhere to be found. Ruh-roh!

Preview 'Game of Thrones' season 3's penultimate episode "The Rains of Castamere" below, and give us your predictions in the comments! Who do you think will get the sword?
