The Widmores - Episode 13 - by Veefre

Veefre wrote:In the season finale Sun finds Charles Widmore and they exchange the following thoughts:

Sun: "You will want to call me. We share a common interest. You know that we are not the only ones to have left the island"

Widmore: "Why would you want to help me?"

This leads me to conjecture several things:

1)
Widmore remarked to Ben early in the season that he was having
nightmares. This, coupled with the fact that Ben "can't" kill him,
leads me to believe that Widmore once inhabited the Island, but left,
and is trying to get back, like the Oceanic Six. Of course he's chosen
a rather brutal way to go about it - sending in commandos to wipe
everyone else out first. Perhaps Widmore once was the leader of the
Others, and he wound up turning the donkey wheel, so now, like Ben, he
can never go back, but if he can't be there, he'll make sure nobody
else can be there either?

2) Jack remarked to Ben that Sun
blames him for Jin's death. Sun now also controls the Paik Heavy
Industries corporation, using settlement money from Oceanic Airlines to
buy a controlling interest. In the past, Paik and Widmore have
partnered on various enterprises, but I think both Sun and Widmore know
that what Sun is referring to as a common interest is really the
Island.

3) It's possible that Sun knows that Widmore, and not
Jack, was ultiimately responsible for Jin's death. And perhaps she
intends to use the power of the Paik company to punish Widmore for it.
Also possible that Sun is working with Ben on this.

Clearly a
main part of the plot of the coming season(s) will be how the Oceanic
Six plus "Bentham" will manage to return to the Island.
