The third episode of Game of Thrones' final season will be a bloodbath. It's guaranteed to feature an epic clash between the White Walkers and the human armies defending Winterfell, and most of episode 2's quiet-before-the-ice-storm episode, "A Knight of the Seven Kingdoms," was devoted to heartfelt, poignant exchanges between characters we've been getting to know for years. They reunited with beloved pets, had sex in a forge, performed meaningful ceremonial gestures for old pals, exchanged deadly weapons, and even sang a mournful song. It was bittersweet because both the characters and the viewers know a whole bunch of people, including some fan favorites, are about to get hacked to bits.
Despite the likely carnage, we do know that one group will be 100% safe: the non-fighting Winterfell citizens who hide deep in the crypt (or crypts, depending on your preference) and wait out the violent conflict. There's no way anything bad could happen to them -- after all, they're in the crypt! At least, that's the argument put forward at various points by characters like Jon, Daenerys, Gilly, and Davos, who ladles out his hearty soup while assuring a young girl, clearly meant to recall Shireen Baratheon, that she's better off below the ground. If everyone is saying the crypt is the best place to go, they must be right? They wouldn't lie to us.
But here's the thing: The crypts are likely a monumentally dangerous place to seek shelter in the midst of an Army of the Dead siege. On a narrative level, we know it's a bad idea because so many characters said that it was a good idea. Clearly, Benioff and Weiss are trying to lull the viewers into a sense of complacency regarding the crypts, setting up the expectation that we don't need to worry about the innocents beneath the ground. Or, the showrunners know most Game of Thrones viewers, accustomed to gruesome and heart-wrenching twists at this point, will figure something bad could happen in the crypts and they just wanted to underline the potential precariousness. Call it foreshadowing or dramatic irony. Either way, stay out of the crypt.
