2) It’s been suggested that the Darlings could be working for Peter Pan from our world. They are his servants, his representatives on Earth, who do his bidding. If so, then possibly the Darlings (or someone else working for the Home Office) are the ones who transported Henry from Arizona to Maine. Possibly, Henry was never officially in Arizona’s child custody services. Maybe his birth certificate was forged by a nurse or doctor who worked for the HO. Otherwise, a baby being transported to a town that doesn’t officially exist would’ve classified Henry as a missing child. So, it could be that someone from the Home Office took Henry by car, rather than a plane (which requires official documentation).
THIS! Just wanted to add that a roadtrip from Phoenix to SB could have taken 2 – 3 weeks, which accounts for his age when he arrived in SB.
