'Game of Thrones' used this codename for Jon Snow during season 6 to keep him secret

HBO
Kit Harington as Jon Snow on "Game of Thrones."
"No one was allowed to say 'Jon Snow' on set, ever. Everyone had to refer to me as 'LC,'" Harington told Entertainment Weekly.
"LC" stood for Lord Commander, Jon Snow's position at the Night's Watch when he was killed on season five.
The ban on using "Jon Snow" was extensive and applied to everyone on the set, according to the magazine. Jon Snow didn't appear in scripts, scene breakdowns, call sheets, and prop or wardrobe materials.
Verbal use of the character's name during shooting was also banned, except when it was part of the written dialogue. Producers even used "LC" while taking among themselves, in case someone not belonging to the production was in earshot.

For his part in the scheme, Harington apologized to fans.
"Sorry! I'd like to say sorry for lying to everyone," he said.
As fans discovered on Sunday's episode, the long-debated question as to whether Jon Snow would be resurrected was finally answered. After Melisandre (Carice van Houten) performed a spell to bring him back, Jon Snow opened his eyes and inhaled the first breath of his second life.
