I don’t know if I believe the reunion will not be a happy one. I think Bae is a very forgiving person and that Rumple is full of regret with this fact. Depending on what happened to Bae since the bean and how he grew up I think can determine how this reunion will go. Also I think other things as well as people will factor into the reunion like where they are, whats going on, as well as Emma and Henry being there. No matter who Bae turns out to be having Emma as well as Henry will change the attitude of he reunion. Bae is seeing two people who would have had completely different lives if he did not use the bean, so that will affect the reunion greatly.
