Game of Thrones ended on an awkward note this week, as Tywin ordered his children to get married, Cersei to a gay man and Tyrion to a child.

Look for these strategic unions to play a key role on next Sunday's "The Climb," as we move into the second half of Game of Thrones Season 3.

Elsewhere:

• Melisandre will pay a visit to the Riverlands.
• Robb will attempt to repair his alliance with House Frey.
• Roose Bolton will decide what to do with the suddenly vulnerable Jaime Lannister.
• Jon, Ygritte and the Wildlings will make it to The Wall.
