Jacob & MIB discover men on the island while chasing a boar

Jacob and MIB are franticly chasing a small boar through the jungle. After a few moments, they hear the boar squeal in pain and MIB tell Jacob to hide. They duck under some plants and watch as three men descend upon the boar. Jacob asks who are they and MIB tells him to be quiet. They are both shocked to see the men, but MIB is clearly more interested.
