To know why Lyanna Stark might have wanted to name her son Aegon with her dying breath, you might need a refresher course on the immense Targaryen dynasty - the family that ruled for three centuries over all of Westeros.

It’s not clear, however, if he was still named Aegon.Ĭonfused? That’s understandable. We know this half-brother at least existed in the show’s universe, because Oberyn Martell famously fought the Mountain partly to avenge his death and the death of his sister. The finale also revealed that Jon Snow’s real name is Aegon Targaryen - a twist that might have confused readers of the books Game of Thrones is based on, since that’s also the name of Jon’s long-dead half-brother.

In Game of Thrones’ season seven finale, Jon Snow and Daenerys Targaryen finally consummated their slow-burning passion - even though the season six finale’s confirmation of the “R + L = J” equation surrounding Jon’s parentage renders their love an incestuous one between aunt and nephew.
