Warning: spoilers ahead! If you haven't watched the final tenth episode of Game of Thrones season six ('The Winds of Winter'), you'll probably want to slap us after reading this. So stop now.

Another day, another fascinating tidbit from the world of Game of Thrones... Yesterday, we got Kit Harington's amusing audition tale, today we get the most solid proof that all those fan theories about Jon Snow's true parentage are correct. Known by GoT obsessives as the R+L=J theory, it basically surmises that Jon Snow is not the bastard son of Ned Stark and some unnamed tavern wench (Starks are too honourable for adultery!), but in fact the secret son of Rhaegar Targaryen and Ned's late sister Lyanna.

The news was finally revealed in the last episode of season six, in a pretty obvious way, but it seems some fans needed concrete proof, which is why we're supposing the official Game of Thrones blog (makinggameofthrones.com) shared this handy infographic.  It's a godsend for anyone who gets easily confused by all the births, deaths, marriages, allies and twincest that the show is ripe for.
