In the Season 7 finale of Game of Thrones, it is revealed that Jon Snow (Kit Harington) is of Targaryen descent. He is originally born as Aegon Targaryen, the bastard son of King Rhaegar Targaryen and Lyanna Stark. This also makes him the nephew of his lover Daenerys (Emilia Clarke). Up until the end of the series, he is a legitimate heir to the Iron Throne.
In the controversial series finale, he is stripped of his titles and sent to live out a life sentence at the Night’s Watch for killing Daenerys.
