After seven long seasons, it was confirmed that Ned’s sister is Jon Snow’s mom, who secretly married Rhaegar Targaryen. Ned covered it up so his buddy and liege, Robert Baratheon, who was obsessed with Lyanna, wouldn’t kill the child. Ned took Jon back to Winterfell to raise him as his bastard much to the hatred of his wife, Catelyn.
If Rhaegar and Lyanna are Jon’s parents, the resurrected Jon is not only legitimate, he’s got some regal blood running through his reanimated veins. As he kicks rocks on the Night’s Watch, one can only hope he’ll make his way to Dany and Tyrion (who are probably his relatives) and ride Rhaegal, the dragon named after his possible pops.
