If you thought we were waiting until this season of Game of Thrones [1] for official confirmation of Jon Snow's father, you were wrong. While we found out Lyanna Stark is Jon's mother [2] in the season six finale, it's not explicitly stated that Rhaegar Targaryen [3] is his father, though many fans assumed it was the case due to the popular R + L = J theory [4]. Rather than drag out the mystery, HBO straight-up confirmed the theory with an infographic [5] on their Making Game of Thrones blog after the conclusion of seaosn six. Take a look:

So, Jon Snow is definitely a Targaryen [6]. This also clarifies how Dany and Jon are related [7], in case you were confused. (Which is totally fine, this is crazy confusing.) Now that we know for sure Rhaegar is Jon's dad, what is Jon's real name [8]?
