WARNING: This story contains spoilers for Game of Thrones Season 7 Episode 6, “Beyond the Wall.”
Tonight’s Game of Thrones―the most stressful episode of the season—saw Jon’s men in an intense face-off with the White Walkers. In a shocking moment, the Night King killed one of Daenerys’s dragons with a single ice spear. In the final scene, he revived it with a touch of the hand, adding an unprecedented threat to his Army of the Dead.
He “has finally gotten his own weapon of mass destruction,” co-showrunner David Benioff revealed in a new “Inside the Episode” segment. He and D.B. Weiss broke down Viserion’s transition into a deadly ice dragon: “[Up] until the end, it’s very close to one of those battles where all the good guys get out the other side, and more or less scot-free, but we knew that killing the dragon was gonna have a tremendous emotional impact, ‘cause over the seasons and seasons of the show, it’s really been emphasized what they are to Dany,” explained Weiss. “We knew that the Night King would see and seize this opportunity.”
The actress added, “My dragon could not have died for nothing, so this is now so important. For the first time, you’re starting to see her defenses broken.”
