Whenever Jon Snow (Kit Harington), the newly minted King of the North, seeks guidance, he thinks back to the words of his deceased father, Ned Stark. When it comes to whether he should punish the disloyal houses of Karstark and Umber, who fought against his rightful rule in last season's Game of Thrones episode “Battle of the Bastards,” he chooses not to hold the children responsible for the mistakes of their parents, and bulldozes his way past the more vengeful desires of his sister, Sansa Stark (Sophie Turner). Yes, Cersei Lannister (Lena Headey) has seized control of King's Landing and summons Jon to take a knee before her, and yes, Daenerys Targaryen (Emilia Clarke) has finally returned to her ancestral home at Dragonstone, but “Yesterday's wars don't matter anymore,” Jon announces. Winter is here, women and children will learn to fight alongside men—a prospect fully backed by the fiery young Lyanna Mormont (Bella Ramsey)—and gold is irrelevant. Only dragonglass (and Valyrian steel) can slay the marching armies of the dead.
