The chó sói, sói that stopped Emma from leaving Storybrooke has not been được trao an identity, but we have been được trao clues enough to determine it. In a sneak peek for tonight's episode,Graham is often featured with one chó sói, sói as his companion. In another sneek peak,the Evil Queen later reveals that he was raised bởi wolves. Since everyone in the fairy tale land was affected bởi the curse,even animals, I believe that the chó sói, sói that kept Emma from leaving is the same chó sói, sói that was Graham's ally and that possibly raised him.
