"Jane’s been a part of Thor’s universe going back almost to the very beginning. She was the initial love interest for Donald Blake, who was Thor’s alter-ego [in early Thor stories]. She was the nurse to his doctor. She’s grown and changed and evolved a lot over the years, become a doctor in her own right. So this to me is not just the next step for her character, but really the next evolution of the core promise that has always been at the heart of Thor’s mythology."
