Of course he’s not f*cking dead. Here are the three most popular theories surrounding the return of the king...
Melisandre will resurrect him
Arya’s time with The Brotherhood Without Banners showed us that red priests can bring the dead back if the Lord of Light wills it. Mel met Thoros in Season 3 and admired his handiwork first-hand in a scene that was written specifically for the show. Her return to the Wall following Jon’s stabbing was perfect timing.
He’ll come back as a wight
Unless Jon’s body gets burned, there’s a chance he’ll return as a member of the undead. We’ve seen the White Walkers’ overtake Hardhome and add countless blue-eyed corpses to their ranks. Could he be next?
