Ep 5. The Door

In Game of Thrones season 6 episode 5, titled "The Door," a new threat emerges in the North as Bran Stark continues to explore his powers as a greenseer. Meanwhile, Sansa Stark and Jon Snow work to gather support for their cause as they prepare for battle against Ramsay Bolton and his army.

In the opening scene of the episode, Bran and the Three-Eyed Raven witness a vision of the Children of the Forest creating the first White Walker. As Bran continues to learn about his powers, he experiences a strange connection with the Night King, who seems to be aware of Bran's presence and is able to touch him in the vision. This sets the stage for the episode's main plotline, which revolves around Bran and his companions trying to escape the Night King's army.

Meanwhile, in the North, Sansa and Jon Snow are working to recruit more allies for their battle against Ramsay Bolton. They reach out to the Wildlings and the small houses in the North, trying to gather as many soldiers as possible for the upcoming fight. They also receive a message from Ramsay, taunting them about their chances of success and warning them that he has Rickon Stark in his custody.

Another major storyline in the episode revolves around Arya Stark, who is still living in Braavos and training with the Faceless Men. She is given a new assignment to kill an actress who is openly mocking the Starks in her play. Arya struggles with this task, as she begins to feel sympathy for the actress and her portrayal of her father, Ned Stark.

Back in the North, Bran and his companions come across a group of Children of the Forest. They learn that the Children of the Forest actually created the White Walkers in an attempt to defend against the First Men, who were invading Westeros. The Children of the Forest created the Night King to be their weapon, but he turned against them and started creating his own army of undead soldiers.

As Bran continues to explore his powers, he is able to use his abilities to see into the past and witness the creation of the White Walkers once again. However, during this vision, the Night King is able to sense his presence and attacks the group, killing the Three-Eyed Raven and many of the Children of the Forest. Bran and his companion Meera manage to escape, but not before learning a devastating secret about Hodor's past.

Overall, "The Door" is a gripping episode that sets the stage for the upcoming battles in the North and provides crucial backstory about the history of the White Walkers and the Children of the Forest. It also explores the ethics of killing and the weight of duty, particularly in Arya's storyline. The episode ends with a shocking twist that will no doubt leave fans eagerly anticipating the next installment.
