I was reading over at darkufo some interesting comments on the episode.
Many (most) of the scenes were mirror images of past season events - the party breaking into to two - some to get a sailboat and some to confront the others (season 2), Sawyer sacrificing himself jumping off the helicopter leaving Jack and Kate, etc.
I still don't understand the MIB rules. He seemed to indicate to Sawyer he couldn't go across water, but he was on the freighter as Jack's dad.
Locke didn't seem afraid of the mortars. I guess Widmore doesn't realize he can't kill "Locke" that way.
