4 Ways Jon Snow Might Find Out Who His Parents Are in Season 7

Since Jon has been physically back at Winterfell (whenever he comes back from Dragonstone, anyway), there's a chance he could make the discovery for himself. Of course, this hinges on there being actual evidence lying around of who his parents are, and a Reddit theory from user jamieandclaire postulates that there's a grave for Jon in the Winterfell crypt with Jon's real parents inscribed on it. It's not terribly far-fetched, and would be very dramatic if the truth was actually literally beneath Jon for years.
