2. Jeor Mormont’s crow has watched Game of Thrones
At the Wall, Lord Commander Jeor Mormont has a crow companion that Jon keeps around after the Old Bear dies. Some fans have found coded messages in the bird’s seemingly random squakings. One theory holds that the crow has told Jon Snow the truth behind one of fantasy’s worst kept secrets: R+L=J.
"“He rose and dressed in darkness, as Mormont’s raven muttered across the room. “Corn,” the bird said, and, “King,” and, “Snow, Jon Snow, Jon Snow.” That was queer. The bird had never said his full name before, as best Jon could recall. Jon, A Dance with Dragons"
The popular theory was seemingly confirmed at the end of the seventh season of Game of Thrones when Jon Snow was revealed to the be the son of Rhaegar Targaryen and Lyanna Stark, and the heir to the Iron Throne. There are countless hints about this theory in the books, but this crow puts it right in front of our faces. Taking the theory further, some fans think that the crow has been possessed by Bran Stark, and that the younger Stark is trying to tell his older brother about his lineage as best he can.
