'Game of Thrones' Reveals Shocking Hodor Twist, Twitter Explodes

HBO

You'll never be able to say 'Hold the door' again.

WARNING: Spoilers ahead for those who did not watch Sunday’s episode of Game of Thrones.

Hopefully you had some tissues nearby and were ready to have your mind blown on Sunday night. Game of Thrones delivered one of its signature twists and now that the TV series has moved past the plot of George R.R. Martin’s books, fans have less of an idea of what to expect.

It all centered around everyone’s favorite companion Hodor (Kristian Nairn), who has been helping Bran Stark (Isaac Hempstead Wright) since day one. Bran pulled a Bran and accidentally alerted the White Walker king and army to his location and those highly motivated corpses came a flockin’.

Unfortunately, they rolled up when Bran was busy in his trance and Meera (Ellie Kendrick) desperately tried to wake him and save him from becoming the White Walker army’s late night snack. They sprinted through the caves with Hodor panicking until they reached the outside.

Meera screamed over and over “Hold the door,” which Hodor repeated time and time again. Bran sees a young Hodor in his trance, writhing on the ground and shouting, “Hold the door, hold the door, Hodor, Hodor,” proving that he has traveled through time to reveal how Hodor first got his name and signature (i.e. only) catchphrase.

When last we see Hodor, he is holding the door as the White Walkers slash through it while Meera carries the unconscious Bran far away as fast as she can. It’s the ultimate sacrifice for a life-long protector.

Following his character’s heartbreaking exit, Nairn spoke with Entertainment Weekly about leaving the show, saying he felt Hodor’s death was appropriate.

“I love it,” he said. “I couldn’t be happier how he has gone out. The interesting thing is it’s kinda left open. You don’t actually see him [die]. It’s implied. So who knows? He may come back as a White Walker, maybe he got away. But it’s a really good way to do it. I couldn’t have asked for a better goodbye to a character I love.”

But fans did not exactly “love” Hodor’s tragic ending, taking to Twitter to express their dismay at losing the kind soul.

Even other celebrities were shocked by the buzz-worthy episode.
