^^^ I disagree I think Hook was going to stay with Emma and her group. I think he was telling the truth, sincerely trying to help Emma and Emma was starting to feel something for Hook to a point where she was going to let emotions cloud her judgment and really couldn’t tell if he was lying anymore. Rather than take the chance and trust Hook she double crossed him. Maybe now he’ll use the information he learned against her but I’m hoping he’ll again try to help Emma proving that she was wrong and she should have trusted him. It’s a shame that what happened with Neal made her so shaky when it came to trusting someone that she put up that emotional wall when she felt herself getting close to someone.
