At the risk of sounding stupid, let me share something with you. Just hear me out. You know the skeletal bodies in the cave? The ones Locke called Adam and Eve? Well, I have a theory on who they are. At the risk of sounding stupid, let me tell you: I think they might be Jack and Kate. Or, as if that wasn't bad enough, I think they might be Desmond and Penny.
I floated this idea with my girlfriend. "HOW?" she exasperatedly asked me, wearing the same expression of anger and despair you may also be currently sporting. HOW indeed? Well, for now, forget the 'how'. I'll have a run at the how in a while. First let me at least defend this madness by explaining WHY.
Why I think it might be Jack and Kate is, well, it's because of those pesky black and white stones. You know, the ones Jack found on the skeletal body. Jack checked the body out, found a little pouch which held black and white stones and then, deftly, he stashed them in his pocket. So here's a thing: We never see those stones again. Jack just takes them. . . and keeps them. . . and never mentions them again. . . and doesn't that just make you crazy?
So in a nice piece of poetry I envisage Jack keeps the stones on his person and then, once dead, he is laid to rest in the cave. His decomposing body turns into a skeleton that, one day, a spinal surgeon from a crashed plane will chance upon. He'll find a little bag holding black and white stones and take them for himself. . . Yes yes, this all depends on Jack getting back to the Island and, not only that, but being back there at a significantly long enough point in time before his younger self will crash land there. . .
Listen: FORGET the HOW for now - just go with me on why I like this idea.
To augment things, Kate (in the episode House Of The Rising Sun, where Adam and Eve are first discovered) very pointedly remarks to Jack that she does not want to be Eve. She was talking about how she didn't want to go and live in the caves, but it's all very ironic, no? Potentially, anyway. And for this idea to make any kind of sense you have to kind of imagine the Island timeline coming full circle, like a complete revolution. And you know what makes this idea nice? The title of the first 'proper' episode of Lost. It's called Tabula Rasa. Clean slate. What you get when you start something afresh.
You might think the idea stinks, but you must admit, it's got a nice thematic quality to it.
So that's Jack and Kate, and if you thought THAT reasoning was bad then wait until you hear about Desmond and Penny. Basically, my 'logic' for figuring that Adam and Eve are the skeletons is this: In Desmond's flashback, in the episode Flashes Before Your Eyes, there's a moment in Penny's flat when, on the table, we can see what looks like two stones; one black, one white. The black and white stones were in Penny's flat!
(And anyone that tells me these 'stones' were, in fact, just bottle tops or something. . . Well, I'm not listening. You're ruining my party.)
And why else could Desmond and Penny be the skeletons in the cave? Well, you know, Desmond's kind of getting this time travel business under control. He's sort of travelled back in time already. OK, sure, only his MIND travelled back but who's to say that later down the line he doesn't learn how to time travel properly? And then, you know, take Penny with him. . .
OK, shaddap. It's not an easy explain. I didn't say I had the answers, I just wanted to share with you! But, just for the sake of it, let me take a run at explaining HOW this could happen.
Imagine that the Island is running on a loop. It exists outside of regular 'time' and 'space' in its own time cycle. If you don't like the idea of it existing outside time and space, consider it nestled within a rift or a slight tear in the time-space fabric. However you grasp it, this could explain the way healing and ageing are warped on the Island. It could explain why Dharma considered the Island a brilliant, giant-size laboratory (like working out how to prevent the Valenzetti equation coming to fruition and ending the world; if they could reverse-engineer the maths on the microcosmic Island these findings could then be used on the real world to save it - like finding a cure for cancer in test conditions before being mass marketed for the general population).
There's all kinds of reasons why this could make a certain kind of sense (and, for sure, all kinds of reasons why it might not).
The idea of the Island on a time loop fits nicely though. Think of Rousseau's distress signal running on a loop (and the numbers playing previously). Think of Desmond's battle to alter a course correcting future (maybe he's not seeing the future at all - just different versions of previous loops). Think of how the whispers could be the voice-echoes of people from previous iterations of the Island loop.
"We have to go back," Jack cries at the end of season 3. How literally do you want to take that statement?
My point is: If the Island is running on a loop, and things can come full circle upon it, this could explain how Jack and Kate, or Desmond and Penny, could eventually be fated to be Adam and Eve - the skeletons in the cave. Just keep your eyes peeled for those black and white stones, that's my advice.
