Ilana is working for”.
It should come as no great shock that Ben kills Cesar the first chance he gets. I suspect that Cesar may have been hired by Charles Widmore, and may also have been the man watching Sayid. Ben may or may not have known this as fact, but when Cesar tells Locke that he is in charge, and not to take one of the boats, Ben kills him.
You will recall, that one of the first things Cesar does, while searching Ben’s office was to take the gun and lie about that to Ilana by telling her it was a flashlight!
This was totally premeditated on Ben’s behalf. He makes Cesar think that Locke should not be trusted. And, while Cesar is looking the other way, Ben does what Ben does best. He steals the gun from him. And, the first opportunity he gets, he kills Cesar!
Now this may seem like some isolated or random incident, however, you would be wrong to think that. Ben could have easily got the boat away from Cesar, by wounding him or injuring him. The real reason he kills Cesar is to get him out of Ilana’s way!
Ben and Ilana exchanged a very knowing glance. There were no words spoken, it was just a glance. A ‘telling’ glance! This told me that Ben knows who she is and why she is there. Ben hired Ilana to arrange for Sayid to be falsely arrested, so he could be placed on board of #316. Ben knew that he would have no chance of getting any cooperation from Sayid, and he was needed to make the trip back to ‘the island’ complete. So, the story Ilana gave about Sayid being arrested at the murdered man’s family’s request is a complete fabrication.
Ilana and her men have guns, and by the looks of it, a lot of them! Guns, that they fully intend to use. They have also developed a ‘code word’ to identify anyone else that is ‘with them’, so to speak. We learned this very quickly when Frank Lapidus couldn’t respond to her code. This would definitely not be Charles Widmore, as he has nobody really left on ‘the island’ that would be on his side within ‘the others’ that would be willing to help him.
The only people Charles Widmore might presently have on his side, that are present on ‘the island’ are Daniel Faraday and Miles Straume. Either one or both of these men, are ‘sleepers’, waiting to move into action once they receive ‘the call’. They may have somebody else that is on ‘the island’ who will turn traitor. Somebody who will receive a message from the future that will convince them, they need to betray their present situation.
Ben is no fool, and if I had to put my money on him or Widmore, I will choose Ben as being the smarter one between the two men, any day. Ben knew when ‘the freighter’ was coming, and count on the fact he also knew in advance what to prepare for, from Charles Widmore this time around. Ben means business and is totally prepared to fend off any attack from Charles Widmore. This time, it would appear that it is Ben who is well armed!
After all, Ben always has a plan!
