'Game Of Thrones' Season 7: Someone Else Knows of Jon Snow's Birth

While Lyanna was giving birth to Jon Snow at the Tower of Joy, there was a handmaid to assist her. Speculations are that she could have heard Lyanna telling her brother, Ned, about asking to keep the baby's identity a secret. If that handmaid is still alive, she could become a key witness for Jon Snow.

In the book version of "Game of Thrones," Ned was not alone when he came up to the tower.  He was with the Howland Reed and they left the tower with Ned's biggest secret, per Nerdist. In the book, Reed is still alive and he is the father of Meera, who is currently with Bran. In the TV version, the character was left to tend to the injured and the dead below the tower, and he was badly injured after battling Targaryen men.

'Game Of Thrones' Season 7: Stark Secret Coming To Light; The Future Of The Targaryens

In the book version, Rhaegar Targaryen was depicted as evil by Robert Barantheon, Ned's best friend. But only because Robert was also in love with Lyanna Stark. Other people who know Rhaegar attest that he's a decent Targaryen.

The reason Ned agreed to his sister's wishes is to protect Jon Snow's identity. At that time of his birth, Robert had already overtaken the kingdom and wanted every Targaryen dead. It was Robert who killed Rhaeger in the book.

It's also possible that Jon and Daenerys would have an encounter in "Game of Thrones" Season 7, where they will both discover the truth themselves. Being a Targaryen, Jon Snow should be able to tame one of the dragons right in front of Daenerys.

Jon Snow's birth was a fulfillment of a prophecy. He is the king that would lead the kingdom in the war with the White Walkers, per Us Weekly. When Daenerys finds out the truth about Jon Snow, two things can happen: she's going to kill her nephew or she's going to form an alliance with him by marrying him. Targaryens are known to marry within the family to keep their bloodlines pure.
