Jeff “Doc” Jensen gives a recap of Cabin Fever over at EW.com, and includes a couple of really great insights, my favorite of which is this:
Locke is born early. At age 5, he takes a test that most likely would have taken him to the Island if he had passed. He didn’t. That same year, Benjamin Linus is born. At age 16, Locke is invited to go to a science camp that again would have taken him to the Island. He refused. About that same time, Benjamin Linus and his father joined the Dharma Initiative. The implication, it seems, is that Ben has been walking the path that was originally meant for Locke. Ben was the contingency plan — the course correction — for Locke’s altered destiny. But Ben is his own person, of course, and he has done things differently from what Locke would have done, and this, in turn, has created further changes in the original order of things — changes that I think a certain ticked-off, Island-deprived billionaire named Charles Widmore is trying to reverse. The scene at the rehab center between paralyzed adult Locke and his wheelchair pusher, the creepy Matthew Abbaddon — who accepted the description of ”orderly” with knowing irony — was meant to suggest one way Widmore is scheming to restore the original order: by getting Locke on that Island and taking back the birthright that was supposed to be his.
I think this is a great theory. I’ll even go so far as to say that they already knew about Aaron and had a hand in getting HIM to the island too.
