MIB thinks he can get off, but obviously needs a plane or a boat or something.
Curious to learn more about widmore now.
Widmore and smokey are prob pals now. Widmore is more than likely still pissed at Jacob for being banished. Still now sure why he wants to be back on the island so bad though.
My question is, why they just don't kill smokey? If Jacob can die, why can't he?
I don't know if they are pals. I don't put up sonic fences to keep out my pals. I'm under the assumption that Jacob is human-ish and the MIB is, while seen in a human form, a spirit-ish type being which I would assume can't be killed by conventional means. I'm also under the assumptions that they are gods (small 'g') or deities who have been given "gifts" but also "curses" (i.e. Jacob can be killed, but only by "humans", but he can be a human....the MIB isn't human but can't be killed). Just kind of basica mythological stuff. I'm not sure the significance of the knife because Jacob was killed by a regular knife, not that special one that the MIB gave Richard (and that Doegen gave Sayid).
Good points. That makes the What does Widmore want? question more interesting. Wouldn't he know he isn't a candidate? So what does he want to do? I am still curious as to why Jacob brought Desmond to the island. Almost has to be something to do with Widmore 
IMO, Widmore’s intentions seem to be his own side which is shaded towards Jacob’s side. I think this because Illana’s group (who I think would be aligned with what Jacob wants) warned Miles that Widmore had bad intentions. And since he’s putting up sonic fences, I can’t imagine that he’s on the MIB’s side. I think, ultimately, he just wants to be the one who leads/has control over the island. He wants the power like he did before Ben banished him. I wouldn’t, however, be surprised if he is actually on the MIB’s side (the sonic fences are a con…which would tie into the episode “Recon”). Maybe he and the MIB have a deal that if Widmore helps the MIB off the island, then he’ll give the Island to Widmore.
To me, Desmond has always been the wildcard. I always thought that he was the character that tied the island to the losties.
