If you’re keeping up with your Game of Thrones theories, you likely know about ‘R+L = J,’ which is not a screwy math problem. At least as the TV show goes, it’s been confirmed by HBO’s ‘Making Game of Thrones’ blog.
If you’re not sure what R+L = J is, it’s surprisingly simple (for Game of Thrones, at least).
In a nutshell, it means that Rhaegar Targaryen (R) and Lyanna Stark (L) are Jon Snow’s real parents (J). In the show, we see that Lyanna Stark is Jon Snow’s mother, but HBO tried to obfuscate her telling Ned who the father was when he came to save her at the Tower of Joy.

So, there you go. If you were like ‘I can’t wait for season seven of Game of Thrones so I can find out who Jon’s dad is!’ HBO just spoiled it for you. It’s not clear why they would have published the infographic as-is, since it seems to spoil a plot line for season seven, but we’re guessing it was an accident — or HBO is just sure we all know anyway so who cares.
