  ==Plot==
  As they keep watch atop the Wall for the coming invasion, Jon and Samwell discuss Jon's relationship with Ygritte during his time with the wildlings. At a nearby camp, the Thenn Warg scouts the Wall using an owl, while Ygritte declares that Jon is hers to kill. In the library of Castle Black, Sam and Maester Aemon discuss Gilly, who arrives at the castle. Their reunion is cut short by horns signaling that Mance Rayder's army has arrived. Jon sees a massive fire burning on the north side of the Wall, and he and his brothers complete preparations for battle. Sam finds Gilly and her baby shelter in the kitchen, and joins the defense after kissing her goodbye.
  Ygritte reports that the castle's entrance is undermanned, and Styr orders the group to attack. As Thorne readies the archers, another horn informs him the castle is being attacked from both sides. Alliser leaves charge of the Wall to Slynt and heads for the castle to battle the Thenns. Slynt proves an inept commander, and Grenn tricks him into going to the castle, leaving Jon in charge. Several giants and a woolly mammoth attempt to pull up the Wall gate, and Jon sends Grenn with men to defend the passage. At the castle, Thorne is wounded by Tormund and is taken to be treated. Sam and Pyp shoot at the wildlings with crossbows, but Pyp is shot through the neck by Ygritte. Sam ascends the Wall, killing the Thenn Warg, and informs Jon that the courtyard is overrun, and Jon leaves charge of the Wall to Edd.
  Returning to the south side of Castle Black, Jon leads the remaining Night's Watch, along with his direwolf, Ghost. Jon kills Styr after taking a severe beating, and is confronted by Ygritte. She hesitates as they smile at each other, and Olly shoots her in the back. As Ygritte and Jon reminisce that they should have stayed in the cave together, she dies in his arms. Edd leads a successful defense, and the wildling army appears to withdraw. Tormund, hit by several arrows, is captured on Jon's orders.
  In the morning, Jon tells Sam that he will go north of the Wall to kill Mance. They find Grenn and his men have died killing a giant, and Jon tells Sam to have their bodies burned. Jon gives Sam his sword, Longclaw, before departing.
