My biggest problem with Neal being Bae/PP is the timing, but your (TheGoldenKey) first post in this thread had me convinced. If Bae went to Neverland first, that would explain the lack of aging. He started aging again when he decided to come to the real world.
I’m still not 100% sold on Neal being Bae/PP, but I would love for the theory to be right.
Neal did wear green throughout the episode. That could be PP.
