undercover for mib
i’m thinking that when widmore comes to the island first, mib convinces him to work undercover for him, at some point mib is going to give a black stone to jacob to show that he has evened the odds.
jacob has richard, mib has widmore but jacob will not know who mib has corrupted.
at some point in time widmore will have an affair off-island, the result will be john locke and when mib sees john lockes name in the cave he will know that he has his loophole and will send the black stone to jacob.
when jacob finds out about widmore he willÂ send richard to young john locke to test him, andÂ then he gets ben to banish widmore from the island……
