'Game of Thrones' Season 3 episode 3 preview: Daenerys buys her army and Theon escapes

If Sunday's "Game of Thrones" episode "Dark Wings, Dark Words" was a little too slow for your tastes, then you'll be a fan of next week's episode, "Walk of Punishment." A new promo for the upcoming episode has been released, and it shows that things are happening fast for the characters on the hit fantasy series.

In the video, Daenerys Targaryen makes a bid for all of the Unsullied in Astapor, Arya finds herself stuck with the Brotherhood Without Banners, Stannis Baratheon begs Melissandre to "make me another son" -- you know, the shadow baby kind -- and Theon seemingly escapes from his captors. Meanwhile, Robb Stark gives someone a stern talking to, Roose Bolton's men threaten Brienne's life and the men of the Night's Watch make it to Craster's Keep. 

Here's the episode's official synopsis from HBO:

Tyrion gains new responsibilities; Jon is taken to the Fist of the First Men; Daenerys meets with the slavers; Jaime strikes a deal with his captors.

"Game of Thrones" airs Sundays on HBO at 9 p.m. ET.
