Sometimes the magic of scripts resides in details...

Visually, this is a very disturbing and realistic-looking creation that shows Melisandre as far more uncertain and fragile than we’ve ever seen before. And there’s something particularly unnerving about watching Melisandre climb into bed, and it took me awhile to figure out why: It’s the relatable simplicity of what she’s doing. We all get into bed. And normally that’s a boring shot to have in a show. A screenwriting rule is you try to avoid transitions like this. I remember watching Don Draper slowly climb into bed during a particularly dull Mad Men episode and ranting internally to the writers: Why show us that? In other words, part of the genius of this scene is that a hugely magical reveal is mixed with a relatable action. Melisandre’s not casting a spell or making some flashy Once Upon a Time-like display. She’s a woman in a cold castle getting under some covers to get some needed sleep while our heroes need her help; far more vulnerable then we’ve ever seen before – and that’s what makes the magic of the scene feel real."
