The fact that the previously very-dead Jon Snow is now very not-dead on Game of Thrones is perhaps one of the worst kept secrets in the show’s six-year history. But that didn’t stop the production team from trying to keep his return under wraps—and they went to some pretty crazy lengths to do so, like banning his name.
According to Entertainment Weekly’s extensive coverage of the return of Jon Snow, during filming his new scenes the cast and crew were forbidden from uttering “Jon Snow” on set at all. The only time the words were allowed to leave someone’s lips was during scenes where Jon’s name had to be said as part of dialogue.
So how did they refer to the character? They simply gave him the nickname “LC,” in reference to Jon’s old title as Lord Commander. Actor Kit Harington was also forced to use the same nickname, as cast and crew was ordered to refer to him as “LC” too, such as when he was called to set, just in case someone not working on the show might accidentally overhear it. (The cute codename didn’t stop people from finding out about Jon’s return well before last weekend’s “shocking” cliffhanger, though.)
