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