My apologies if folks have already addressed this, but it seems obvious to me that Sawyer and Jack seem to be reflecting the roles of MIB and Jacob respectively. In both "The Last Recruit" and "The Candidate," we see even more intensity in the ever-growing conflict between the two characters. Jack wants to remain on the Island and Sawyer wants to leave. In last night's episode, Jack "saves" Sawyer and pulls him back onto the beach. Although he was only trying to rescue Sawyer, in a sense, Jack was basically taking Sawyer back to the Island against his will. Kind of symbolic of Jacob keeping MIB trapped on the Island??
