How Ben got back to the island.
I was watching season 5 again and I was thinking. Eloise hawking says to Jack that he has to recreate the original flight as much as possible and that Jack must give John Locke an item of his fathers so that Locke can act as a proxy (substitute) for Jack’s father on flight 316. Jack ends up giving Locke his father’s shoes. I was thinking that Ben might have gotten back to the island by being a proxy for Jin as he had the wedding ring of Jins that he took from Locke when he killed him. Ben saved Locke at first but then murdered him, I thought this was only once he had heard Locke mention Eloise hawking but it was probably once he knew that Locke had brought back Jins wedding ring with him. Maybe something similar for Hurley / Charlie as Hurley had brought back Charlie’s guitar case. (Which was incidentally given to him by Jacob)
What dya think??
