Every week when I watch LOST, I obsess over trying to fit the new pieces of the puzzle into what we already know ... after last night's episode I am convinced that Ben is "Son of Dharma" ... he is child of some long dead Dharma members ... and during the Dharma days, they discovered or created the "box" that makes all your wishes come true and they discovered the amazing healing properties of the island ... unfortunately the island does have its side effects, for example the men or women (or both) are infertile, so they have to recruit Juliet to fix that, but it doesn't seem to be working for Ben and his people so they have to "steal" their children to continue their lifestyle ... also, Ben seems to have a mind control quality about him, very cultish, to me it seemed that he brought John Locke to him with the C4 to do his dirty work ... so that's how I fit last night into the puzzle ...
