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