I went back to look at the pilot episode and I come the conclusion that Jack hasn’t been Jack since the plane crashed. When we first see him he is lying in the bamboo field and he opens his eyes. We next see Vincent and he is just watching Jack and then he just runs off. The next time we see Vincent he is hiding in the bushes just watching as Jack, Kate and Charlie hike through the jungle in search of the planes cockpit. He remains out of sight trying not to be seen. What could make a dog act in such a way? Does he know something that we don’t?
This just makes me think of Doctor Who because of two things that seem to be critical when it comes to Jack. First the mark that was on the Marshal’s neck located in the same spot as the blood spot on Jack’s neck was a control device. Second the person that made the decision at the Chaos Pool that was fed by the waterfall was the same person that was revealed not to be the person that they were pretending to be. Looking into the mirror in the Doctor Who story revealed who the person really was. Is Jack not who we think he is? Has Jacob handed over the reigns of the island to an imposter? From the very beginning I have believed that Locke truly believed in the island. When we found out about the candidates I believed that he should be the one to take over the job. So the only question that remains is who is pulling his strings? Is this the twist that will have us all talking on Monday? What secret agenda is being perpetrated by Jacob or Locke that will turn out to be key to the entire plot?
Also I watched episode three and was reminded of another Doctor Who similarity. When the Key to Time series first started with the Ribos Operation we see the Doctor in his TARDIS and he is blowing a whistle. It turns out he had just made a whistle that he could us to call K-9 if he ever needed him wherever he was. He blows the whistle and K-9 responds with “master” and the Doctor utters the words “it works.” Well Locke made a dog whistle out of wood and is able to lure Vincent in so that Walt can be reunited with his dog.
I don’t think Vincent would have ever come in on his own had Locke not made the whistle. I don’t know why he acted the way he did but I believe that it has everything to do with Jack or whoever it is that is pretending to be Jack. Note: all of my assumptions come from the fact that I am basing all my theories on the Doctor Who: The Face of Evil and The Key to Time series. I think this is the reason that they are going to replay this episode. Where was Jack at during the time that Kate was running for her life and after he had freed Charlie when they were being chased by Smokey?
