If you aren't caught up with Season 6 of HBO's Game of Thrones yet, there will be massive spoilers below. Season 6 came to an end on Sunday night with the season finale episode The Winds of Winter, which fans will be talking about for quite some time. As many expected, a longtime fan rumor was finally confirmed, as we learned who Jon Snow's (Kit Harington) mother really is, but now we have confirmation about who his father is, too, although most already knew. This is your last chance to avoid spoilers, so read on at your own risk.

After the resurrection of Jon Snow by Melisandre (Carice Van Houten) in the second episode of Season 6, many fans thought that we would finally learn the truth about Jon Snow's parentage. Early on in both the TV show and the novel series by George R.R. Martin, it was established that Jon Snow is a bastard son of Ned Stark (Sean Bean), after a supposed tryst while Ned was away at battle. Since Ned was one of the most honorable men in Westeros, most fans didn't think Snow was actually Ned's bastard, but actually the child of Rhaegar Targaryen and Lyanna Stark, Ned's sister. While it was confirmed in the finale that Lyanna is in fact Jon's mother, an official HBO infographic from Making Game of Thrones confirms that Rhaegar Targaryen is in fact Jon's father.

We learned the truth about Jon Snow's heritage towards the end of the finale, when Bran Stark had a greensight vision from the Tower of Joy. We had previously seen a part of this scene earlier on this season, but this new footage showed young Ned (Robert Aramayo) rushing to his dying sister Lyanna's (Aisling Franciosi) aid. During a pivotal scene, she presumably tells Ned who the father of this child is, although we don't hear what she says, telling Ned that Robert will kill the child if he finds out. While fans familiar with the R+L=J theory already believed the father was Rhaegar Targaryen, this infographic fully confirms the theory once and for all.

Now that fans know Jon Snow isn't a bastard, we'll have to wait and see how long it will take Jon Snow to find this out for himself. Before Bran Stark had his greensight vision, he was dropped off just before The Wall and Castle Black by Benjen Stark (Joseph Mawle), because Benjen couldn't go any further. It seems likely that Season 7 will show both Bran and Meera (Ellie Kendrick) heading to Castle Black, and then, most likely, to Winterfell, to reunite with Jon and his sister Sansa (Sophie Turner). Jon's heritage does give him a claim to the Iron Throne, which is currently occupied by Cersei Lannister (Lena Headey).

This infographic not only confirms Jon Snow's father, but shows how members of the Starks, Lannisters and Targaryen's are connected to each other as well. As with most story developments on Game of Thrones, this infographic is quite complex, but should help you pass the time as we begin the long wait to Season 7. Take a look at this inforgraphic below, and stay tuned for more on Game of Thrones Season 7.
