Widmore & The Purge
The purpose of the purge was to get rid of people who knew stuff that could cut into Hanso’s profits.
Widmore went from shoeless island dweller to super rich in just 12 years after the purge. Has ties w/Palik (violent mob guy) and just doesn’t seem to be ‘Mr. Nice Guy’. My bet – he has Team Hanso funding (munitions anyone?).
What if some slimy purge-surviving egotistical somewhat maniacle creep … like Radzinsky … was a ‘double agent’, so to speak, who sought out an equally power-freakish Other, who might also be aware of time travelers ‘cuz his lady killed his son and had a book w/all kinds of formulas … like Widmore. (You know … photographic memory Radzinsky. Wonder how long it’d take him to learn a book like that?)
Anyway, what if a deal was made that his wife and son got off the island (conveniently clearing the way for him to be Other leader + a little money and maybe a few off-island days R&R where he conceived a Penny – maybe even ‘he island itself) in exchange for some information AND a truce with the Others. Widmore, now corrupted and rationalizing he’s helping his (Other) people does his stealth operations while Radzinsky absorbs Dharma knowledge … until the day comes that Hanso wants to collect on his investment and clears the way for being the only one who has the info – by ordering the purge. (Seems a munition guy just might have access to poison gas.)
The Others used the sub to get off island, presumeably acquired after the Purge – which happened Dec. 19, 1992. Penny’s clearly older than that. It doesn’t take a Dharma-genius to know he got off the island somehow (and not w/FDW). Her off-island birth is enough to prove Widmore made a deal with the devil, so he was banished. Like Napoleon, it wasn’t the banishment – but the loss of power – that got to Widmore.
And now … he’s ba-aaack. Not as an agent of ‘The Monster’ – but as one who knows it’s weaknesses.
