Somehow, it seems like we've always had the people of Westeros in our lives, and looking back at characters in season 1 of Game of Thrones , we can at least be certain that it's been a long, long time since we first met some of these plucky, young whippersnappers. From Arya to Sansa to the Mother of Dragons herself, the Game of Thrones cast has changed a lot since season 1 . Age is a funny thing that way.
