I think the enchanted forest thing is a dead giveaway that somehow these three are either the enchanted forest counterparts from the past to save the future of these three are separated from all their family in the premiere and end up on the Enchanted Forest.
Why would characters in the past be in the future? So we have time travel for just these three characters into the future to meet up with a present day Henry in the future?
