EP: 104 Walkabout

WHAT WE LEARNED:

1. Locke is a hunter and was a paraplegic before the crash.
2. Jack is considerate but not religious.
3. Shannon uses people.
4. Charlie is a pigeon.

Questions:

1. Why didn't the murdering Smoke Monster kill Locke? He seemed to actually get along with it. There is something hugely wrong with Locke...
2. How did Locke's legs get cured like that? Why doesn't Locke tell anyone?
