LOST: Jack/Desmond

And again:

"I acknowledge it's something new either way. Hallucination just makes the most sense to me as opposed to be any sort of transmigration, be it physical or into Jack's consciousness. My theory is that LAX-Jack is experiencing some sort of mental "deja vu" about his alternate existence. The injury on his neck could have been a physical manifestation of the same phenomenon. My prediction is that he'll have more experiences like this, and this could lead to his actively taking steps that might bring the universes together. Hence, I do think hallucination has a point, if it's a direct offshoot of The Incident." Mr. Darth

One: Totally agree with the deja vu experience -- let's look at the side by side. If you havn't seen this by now, I would be surprised, but this is a video of the two plane "crash" scenes all synched up I think we are supposed to read this as Jack having some kind of twitchy feeling, even the look on his face at the beginning of the clip is telling. For us it's not weird because for us, we are jumping back through the entire show to the (possibly the first seconds) very beginning of the narrative -- total "Holy Shit" moment, but it shouldn't be holy shit for Jack, not if he doesn't remember anything -- shouldn't be special to him at all. So that look of recognition (or?) in his face is supposed to be deep and meaningful (yup, yup, agreed).

Two: The neck thing was foregrounded heavily -- we are encouraged to wonder about that too. There is some kind of physical connection between the Jacks, and thus between the universes (universi?)

But -- well, first I like your idea about the splintering consciousness, that's berry interesting. But, I said maybe Desmond is appearing in Jack's subjectivity, and I think you took what I meant -- i.e. Jack can see him but no one else can. However, this would be Desmond actually contacting Jack (for why I don't know yet); but by saying hallucination, I think you're saying that Desmond has nothing to do with this, will have no memory of it, that the Desmond that Jack sees is merely a figment of Jack's imagination, Jack's already malfunctioning brain playing tricks on him, by showing him a man he doesn't know? What for? Will Desmond be the discontinuity that leads Jack to realize that there are two realities -- the first piece of "something ain't right"? If that's where you going, I'll take that as a viable third option, or do I misinterpret your idea?
