Game of Thrones: What Randyll and Dickon's Fate Means For House Tarly

Sam is, of course, the first Tarly we meet on the show. He is actually the eldest son and technically should be the heir to the castle. However, he gives up that right when he joins the Night's Watch. Hoping to become a maester, he begins working at the Citadel — though he's tasked with menial labor more than anything else. Fed up, he leaves during "Eastwatch" to do . . . something else.
