Game of Thrones Season 3 heads into the second half of the season with Season 3, Episode 6: "The Climb" (May 6). But what can you expect from the episode? We've got your spoilers right here.

Tywin's plan. HBO's official synopsis says that "Tywin plans strategic unions for the Lannisters." We assume that's a continuation of the final scene from Episode 5, where he declared Tyrion was marrying Sansa and Cersei Loras, whether they liked it or not (hint: they did not). Tywin still needs to get the Tyrells to agree with this plan, which hopefully means we'll see a Tywin-Lady Olenna scene. Please, Game of Thrones gods?

Relatedly, we know the Sansa-Tyrion marriage goes forward in the May 19 episode (Episode 8: "Second Sons"), and Shae is definitely not happy about the arrangement (though, based on the press releases, that might not come into play until Episode 7).

Melisandre's plan. In this episode, "Melisandre visits the Riverlands." Hmmm ... could she be going to see her fellow Lord of Light worshipers, the Brotherhood Without Banners? And, if so, what does that mean for Gendry? After all, as one of Robert's bastards he does share Stannis's blood...

Does Robb compromise? Robb, who wants the Freys to side with him despite that time he totally disregarded their marriage agreement, "weighs a compromise to repair his alliance with House Frey."

Jaime's fate decided. Meanwhile, "Roose Bolton decides what to do with Jaime Lannister."

Climb the wall. Finally, Jon, Ygritte, and co. "face a daunting climb" — up the Wall itself!

This episode was written by executive producers David Benioff and D. B. Weiss.
