HBO makes a television program called Game of Thrones, which is increasingly loosely based on a series of books called A Song of Ice and Fire. Both of these things have enormous fanbases, who are prolific writers of theories about the story's 10,000 characters.

[Spoilers for all that stuff.]

Amongst fans of both Game of Thrones and A Song of Ice and Fire it has been widely suspected for some time that Jon Snow is not actually the son of Ned Stark and Some Rando, but actually the love child of Ned's sister Lyanna and the Targaryen prince, Rhaegar, both of whom are RIP-ing. Why? Because it's more dramatic this way, and it's nice to think of Ned as incapable of adultery (RIP to him, and to his wife, and to most people he could have adultered with).

More importantly, this makes fan favorite Jon a contender for the Iron Throne.

RIP Ned, Ned's wife, Ned's sister, Ned's sister's baby daddy, mostly everyone

The theory was mostly confirmed on Sunday night when Lyanna was shown giving bloody birth to a baby with brown eyes, whispering something about how her fiancé (Robert Baratheon) would probably want to kill it, then dying. The next cut was to grown-up Jon Snow's brown eyes. It's a good shot. Honestly, he looks incredible. Like, this is the face of a man who would doggedly pursue me, you, or anyone, because he has so much love to give.

Anyway, in case you hate subtext, HBO has released an infographic which clearly labels Rhaegar Targaryen as Jon Snow's father and Lyanna Stark as Jon Snow's mother. For Jon / Sansa shippers there is a more important revelation that is not displayed on the chart. Jon Snow and Sansa Stark are cousins, not siblings. ;)

Here it is:

Now we're left to wonder how Jon will find out about this steamy little secret, since the only person (that we know of) who could tell him is hundreds of miles away on a sled.
