Locke and Ben return to the Dharma mass grave, Hurley sees it for first time

After Horace tells Locke to find him in his dream/vision, Locke goes to the Dharma mass grave to find him. Hurley sees the grave for the first time and is noticeably disturbed. Again we see some of the bodies in the grave including the generic Dharma logo on one of the jumpsuits as well as the skull with the bullet hole.

"Walt" returns to help Locke

Here are screens from the scene of Locke in the mass grave about to commit suicide. Walt appears before he pulls the trigger to inform him that he still has work to do. What work? Putting a knife in Naomi's back? We'll have to wait and see.
