Since Jon Snow’s parentage was confirmed, people have been wondering if he is truly a bastard. Personally, I would say he is legitimate for a number of reasons. To begin with, even though Jon’s father Rhaegar Targaryen was already married to Elia Martell Targaryens have been known to perform polygamous marriages in the past. Aegon the Conqueror had two wives while Maegor the Cruel had six. Due to this, it is very likely that Rhaegar rekindled this Targaryen tradition and took Lyanna Stark as his second wife. Therefore, Rhaegar would have married one girl from the south and another from the north. Also, if Jon Snow was truly a bastard, Rhaegar would not have bothered to have the best of the Kingsguard (including Ser Arthur Dayne) protect a common bastard. As a result of these factors, I think Jon Snow is a legitimate Targaryen and the true heir to the Iron Throne, but he doesn’t know it yet. Therefore, his real last name would be Targaryen instead of Snow and he would secretly be known as the Dragon of Winterfell. The question is whether or not Jon Snow will find out who he truly is and how he and House Stark in general would react. What do you think?
