I just rewatched this episode, along with all the others

, and really loved it (again!). I love the Widmore/Ben relationship, the fact that imo the Island wont let them die and that Widmore not just predates dharma, but Ben as well (BOY!).
I saw some mention in the thread about Widmore being one of the natives, and another saying he ran Dharma. One way I could see either one working is: Ben told Hurley that he was ordered or doing someone's bidding when he killed all the dharma people...so Richard? Jacob? Was this incident what led Widmore to losing the island? Did he lose in the capacity of CEO or was he banished, lost power, etc?
Someone humor me

I never thought of Widmore as having been one of the natives, but it's possible. Could he have been in charge at the time Ben came to the island as a boy? Maybe after the purge, he had to move the island so that Dharma couldn't send people to re-take it. Ben said once he moved the island, he wouldn't be able to go back himself, so maybe Widmore had planned for someone to come get him after he moved the island, but then Ben decided to keep it hidden from him so that he could stay in charge instead.
Of course it's always possible that Widmore is just a powerful businessman looking to take control of the power of the island, but I feel they are definitely leaning toward him being more 'supernatural' somehow, maybe along the lines of Richard the ageless.
