Oberyn Martell, the Red Viper, talking with Varys. Ygritte, Tormund Giantsbane and the Wildlings attack Castle Black which is defended by Jon Snow, Alliser Thorne and the Nightswatch. Theon's sister Yara Greyjoy and the Iron Islanders rescue Theon who is shown in armor. Rast leaves a baby in the snow for the White Walkers. Arya, Brandon, Littlefinger and Hodor are still around.

The Red Viper and the Mountain fight in a trial by combat over Tyrion's guilt.
