Perhaps Henry ends up getting sent to Neverland alone, maybe courtesy of Rumple, and becomes press ganged into being one of the Lost Boys. He would then meet Peter Pan. Whereas Peter and the Lost Boys want to stay young and play in Neverland forever, Henry wants to go home and grow up. Since Peter nad the Lost Boys are anti-adult, it wouldn’t make sense for Emma and company to be with Henry.
However, since Emma doesn’t want to leave Henry in Neverland, she finds a way to get there with Neal. Hook tags along too as their guide. Bae, perhaps being a former lost boy, would know where Peter’s hide out is whereas Hook doesn’t. Both Hook and Neal would have to go because Hook has the means to get to Neverland (his ship enchanted with fairy dust) and Neal would have the local knowledge (where Peter Pan’s hideout is).
During the course of season 3, the CaptainSwan/Swanfire triangle can play out with Hook and Bae trying to one up each other in Emma’s affections.
All magic comes with a price!
