Anyway, with that Jacob scene we did get to see him for a brief second. He has long shaggy hair and possibly a bear, and looks very old. Before Ben opened the door to the little hut, I was half expecting to see an old mumuified corps sitting in a rocking chair (like Mrs. Bate's from Physcho), so it was funny when I found I was half right with the rocking chair thing and found the next best thing to a mumified corps, nothing. I really wasn't expecting that scene to pan out how it did though, I thought Locke would pull out his gun and shoot at the chair and that Ben would go nuts screaming "You killed Jacob!"
Honestly though, how weird was the Jacob thing when we have been subjected to smoke monsters and visions of dead people for the duration of the entire series? It was no shocker to me, in fact, I would not be surprised if Jacob turns out to be the smoke monster. I am sure there is some connection there. Remember when the writter said that in the end it would turn out there was nothing supernatural about the show, and that everything would be scientifically explainable. I wonder if they threw that out the window, or if they are going to pull at the strings of some pretty off the wall theoretical science. I am thinking the later. Especially with the book The Third Policeman in mind.
