I just realized something significant about House Targaryen! Even though Daenerys is dead and “Jon Snow” is exiled, they are not the last of the Targaryens; far from it! Allow me to explain. Over a hundred years before the main story of Game of Thrones, Aegon the Unworthy legitimized ALL of his bastards on his deathbed. This led to the five Blackfyre Rebellions. However, Daemon Blackfyre, Aegor “Bittersteel” Rivers, and Brynden “Bloodraven” Rivers were not Aegon’s only bastards of noble birth and not all of Aegon’s bastards of noble birth were acknowledged. Also, even though Aegon had nine prominent mistresses, the exact number of women he had children with are unknown even to him. He definitely had more bastards than even Walder Frey or Robert Baratheon and he legitimized ALL of his bastards including the ones who were unacknowledged or of low birth. The only catch is that these legitimized bastards and their descendants don’t know who or what they are. Even though most of Aegon the Unworthy’s noble bastards mostly killed each other off, his unacknowledged and low birth bastards and their descendants still live. With no one knowing who they are, they will not be hunted and killed like their known relatives. Because they were legitimized, they and their descendants are not bastards anymore. Due to this House Targaryen still lives, but only in secret.
