What does everyone think of this idea?

For Locke to miraculously get up after being shot in the ditch, and then to finally get to see Walt again....

I have a feeling this is a play of Jacob.

Thoughts?

I also thought it was either a manifestation of Jacob or Smokey.

Jacob or the Island. Not really Walt. A manifestation of someone Locke trusts.

Walt is the replacement for Jacob, Locke is the replacement for Ben.

Guide and protector respectively.

Also thought Walt was Jacob.....someone Locke would respond to....

One thing that points to it being The Island/Jacob/Smokey and not a teleported (per Ms. Kluegh) Walt was that Walt was referring to John Locke as "John" and not "Mr. Locke" like he always had season 1.

Walt is the replacement for Jacob, Locke is the replacement for Ben.

Guide and protector respectively.

Maybe James can be saved and be a replacement for Old Smokey since he's got his kill on.
