Everything We Know About Game of Thrones Season 8
Jon is the Rightful Heir to the Throne
We learned on season six that Jon was the son of Rhaegar Targaryen and Lyanna Stark. At the end of season seven, we learned that Rhaegar and Lyanna were married before they died. That means that Jon, as Rhaegar’s only living son, would inherit the Throne instead of Dany.
Whether that information ends up being relevant or not remains to be seen. It is interesting to know that a boy who was raised as a bastard could end up ruling the realm. It may impact how he treats his subjects, and lead him to be a more just, even-handed king.
