16Honorable Mention: Rhaegar Targaryen
The eldest son of the Mad King, Rhaegar Targaryen still stands a reasonable chance of showing up before GoT comes to an end. As the secret father of Jon Snow, he plays a pretty pivotal role in the very events that Bran went back in time to
witness at the end of Season 6. Bran’s flashbacks have been relatively scarce—only hinting (however strongly) at key plot points without spelling everything out entirely. That could definitely mean a no-show from Rhaegar, but it could also mean we’ve been building up to a showstopping appearance the next time Bran goes full three-eyed-raven. In the end, we really won’t know until we know, so Rhaegar gets an honorable mention here.
Before Robert’s Rebellion, Rhaegar was the tall, handsome prince of the Iron Throne, beloved by his subjects and well known as a valiant renaissance man. He was married to Elia Martell, but he declared Eddard Stark’s sister Lyanna the Queen of Love and Beauty at the Tourney of Harrenhal and subsequently abducted her—an action that seemed to clash with his good reputation. While his motives for kidnapping and conceiving a child with Lyanna remain a mystery, the birth of his bastard son make him one of the most influential figures in the Song of Ice and Fire.
