As King Charles III was crowned in Westminister Abbey Saturday, viewers worldwide got a chill, or a chuckle, out of an unexpected sight. Right after the king’s guards processed into the abbey, a lone figure wearing a black hooded robe and holding a long stick that could have been a scythe walked by the abbey’s open door. Had the Grim Reaper made an appearance at Charles’ coronation? Was it an omen? A prankster? A warning? Part of the ceremony? An AI deepfake? No one knows for sure, and speculation was rife. Some even said it was the ghost of Charles’ celebrated late wife Diana. But whoever or whatever he was (and gosh, Grim, big apologies if I’m misgendering you), he was a welcome sight for reasons that have been insufficiently appreciated.
