Rast is a recurring character in the first, third, and fourth seasons. He is played by guest star Luke McEwan - who changed his acting name to Luke Barnes at the start of the third season - and debuts in "The Kingsroad." Rast is a ranger in the Night's Watch, and takes part in the Great Ranging Beyond the Wall. Though he is disliked for bullying and his past as a raper, he is generally treated patiently by Jon Snow, Grenn, Pyp and Eddison Tollett, until he betrays the Night's Watch in the Mutiny at Craster's Keep. Instead of helping defend Craster's Keep with the rest of the Mutineers, Rast instead flees the ongoing battle, allowing his former brothers to be massacred by the Night's Watch before being mauled to death by Ghost, the same animal he tormented.
