There are only a few months to go before fans learn how Game of Thrones will end... and who will be seated on the Iron Throne when it does. The eight and final season premieres in April, and fan theories are flying as to who is most likely to become the final ruler of Westeros. Of course, there are some obvious choices - Daenerys Targaryen, the woman who has been aiming for the throne since the start. Jon Snow, aka Aegon Targaryen, who is the rightful heir.
