The Watchers on the Wall

"The Watchers on the Wall" is the ninth and penultimate episode of the fourth season of HBO's medieval fantasy television series Game of Thrones. The 39th episode overall, it was written by series co-creators David Benioff and D. B. Weiss, and directed by Neil Marshall. It first aired on HBO on June 8, 2014.

Like season two's "Blackwater" (also directed by Marshall), the episode focuses exclusively on one storyline: the wildling assault on Castle Black at the Wall, and the Night's Watch defense, led by Ser Alliser Thorne and Jon Snow. In the episode, Mance Rayder's army attacks Castle Black from both sides as the undermanned Night's Watch struggle to fight them off; Ygritte is eager for revenge against Jon; and Gilly hides from the battle. The episode achieved a viewership of 6.95 million during its initial airing in the United States, and received positive reviews from critics and audiences.

For the episode, Neil Marshall was nominated for the Primetime Emmy Award for Outstanding Directing for a Drama Series.

Plot
As they keep watch on the Wall, Jon and Samwell discuss his relationship with Ygritte during his time with the wildlings. In the library of Castle Black, Sam and Maester Aemon discuss Gilly, who later arrives at the castle with her baby. With a massive forest fire to the north, the brothers continue preparations for battle. Sam finds Gilly shelter in the kitchen and promises her that he will not die. Their reunion is cut short by horns signaling that Mance Rayder's army has arrived.

At a nearby camp, a Thenn warg scouts the Wall using an owl, while Ygritte declares that Jon is hers to kill. Ygritte reports that the castle's entrance is undermanned, and Styr orders the attack. As Thorne readies the archers, another alarm informs him the castle is being attacked from both sides. Thorne leaves Slynt in charge and heads down but Slynt proves incapable and Grenn tricks him into also going to the castle. Two giants and a woolly mammoth then attempt to open the outer gate and Jon sends Grenn and others to defend the inner gate. At the castle, Thorne is wounded by Tormund. Pyp shoots at the wildlings with crossbows while Sam reloads for him, but Pyp is killed by Ygritte.

Sam ascends the Wall and informs Jon that the courtyard is overrun, and Jon leaves Edd in charge. Descending, he leads the remaining Night's Watch, and has his direwolf released. Jon kills Styr and is confronted by Ygritte. She hesitates and Olly shoots her in the back and as she dies in Jon's arms, they reminisce. Tormund, hit by several arrows, is captured on Jon's orders. Above, Edd leads a successful defense and the wildling army withdraws.

In the morning, Jon tells Sam that he will go north to kill Mance. They find Grenn and his men have died killing a giant, and Jon tells Sam to have their bodies burned. Jon tells Sam to mind his sword before departing.

Critical reception
The episode received positive reviews from critics and audiences.

James Hibberd of Entertainment Weekly wrote, "[the episode] was an intense rousing hour of heroism and heartbreak that set a new bar for what this show – and TV – can do." Another positive review came from Terri Schwartz of Zap2it.com, who wrote, "As the most expensive episode of the series, the Battle at Castle Black felt like an equivalent of The Lord of the Rings: The Two Towers Battle of Helm's Deep." David Malitz of The Washington Post was more negative about the episode, writing, "Aside from the major moment with Jon Snow and Ygritte it was hard to feel too emotionally invested in anything that happened. And as visually exciting as it was to watch everything unfold, the ending was surprisingly unfulfilling."
