Alfie Allen, the actor who played Theon Greyjoy in the series The Throne of Swords , said that authors , David Benioff and DB Weiss, they used to do jokes to the actors . For example during the making of the second season they gave him a fake script in which his character died prematurely.
If you remember the numerous deaths of the first seasons of The Throne of Swords had become a kind of catchphrase. Allen was disappointed but was not too surprised to read that Theon was killed by Bran. The sick boy should have stabbed him shouting “This is my Winterfell, not yours”. Many cast members believed that Allen would be upset by the joke, but the reality was quite different, as he reacted with great professionalism to the prospect of seeing Theon die and went to sunbathe to relax.
Allen also added to his story that a similar joke also fell to Kit Harington, the actor who The Throne of Swords played John Snow. Benioff and Weiss gave him a fake script in which Snow's hair was burned by a stranger. From then on the character should have remained completely bald.
