LOST the Final Season

In watching the final season of LOST there is this bitter sweet feeling with it all ending so soon. I want to put a blog together with a number of questions (4, 8, 15, 16, 23, or 42) I get out of each episode and since this is the final season, we'll see if my questions and theories are answered. The fourth episode of the season is called "The Substitute" with John Locke as the main character explored.

My questions from this episode are as follows:

1. How did Locke get into the wheel chair if he loves his Daddy now? (Being invited to the wedding and his picture was on his desk)
2. Why doesn't Kate have a number when she was touched by Jacob, but Miles, Claire, the Freighter folks, etc...all have numbers and they weren't as integral to the story?
3. Could the Kwon name be Jin and Sun's daughter?
4. Should we trust the Man in Black? (I think we should approach him the same way Sawyer did when he got off the ladder...squinty eyed with skepticism)
5. Is the boy in the jungle Aaron or Young Jacob? (could be Charlie, Penny and Desmond's little boy)
6. Why was he bloody in the presence of Richard who couldn't even see him and not bloody when Sawyer could see him? (It's as if the island wants to appear more pleasing to Sawyer during his candidacy)
7. Who lived in the cave?
8. There is no way that Abbaddon, Ecko, and Walt cannot reenter this picture, where are they and how can then help us finish this story?

Let's see if we get any answers next week :)
Namaste
