You are correct GF. It seems Locke was paralyzed by someone else. Also on Locke's desk their is a picture of him and his father. Same father from the old flashbacks.
Also, if you believe that these flash-sideways are caused because the bomb went off...a big hole in that theory is seeing Ben as a teacher. If the bomb went off...and the island sunk...then you would think Ben died. We know he was on the island when the bomb went off.
Cool seeing Hurley meet Locke. And Hurley still own the company that Locke worked for.
The numbers are back. Why wasn't Kate mentioned? Also 23 Shepard....could that mean Christian and not Jack?
Finally, coming from a mixed religious family, I'm not one for reglion...and don't really get into it when it comes to lost. Even though it very well could play a factor. But I found this very interesting.
The ladder New Locke and Sawyer went down lead to Jacobs cave. You could call the ladder, Jacob's Ladder -a ladder to heaven, described in the Book of Genesis, which the biblical patriarch Jacob envisions during his flight from his brother Esau.
