JBear is a guardian of the Book of Stories. He becomes Ava’s mentor, guide and friend as she travels into Grimm World and beyond. J Bear is loyal, caring and, like Ava, courageous. Unlike Ava, however, J Bear believes it’s better to be cautious. He and Ava often disagree on how to handle a dangerous situation, but he always supports Ava’s decisions because he knows that this is her adventure—and the best way for her to grow is to make her own decisions and learn from her own mistakes.
