So while Bae may have subconsciously been plotting Phoenix stars for sorta unknown reasons, it is at all possible that it’s more of PP’s manipulation?
While I think that Bae made the constellation map, I think PP possibly left him clues, which helped Bae figure out “another way” to leave the island. Peter Pan told Henry his birth was no accident, and that PP always intended for Henry to be born of light and dark. That means PP always planned for Emma, true love incarnate, to have a child with Baelfire, the spawn of the dark one. I think that PP planned for Henry to be born in Phoenix, Arizona, where Emma was incarcerated, because of the huge symbolism of Henry causing magic to be reborn. The way between Neverland and Earth being the constellation of the pheonix would add to that level of symbolism. Having said that, I do see huge SF symbolism in the phoenix constellation rising from the ashes of a palm tree coconut. SF is being reborn. Emma’s tagline for S3 was “Believe a Lost Girl can find her way home.” Baelfire’s map is showing her the way home, home to her figurative Tallahassee.
