Is Sayid's girlfriend from his flashback still alive?
Perhaps Ben has HER captive somewhere and
of course Sayid would do anything to get her
back. Sayid does not have much luck dating,
with Shannon dying and him shooting the spy,
sorry I forget names. LOL.

Whatever is going on, I feel that Sayid is a good guy-with pure intentions. If he and Ben are in an alliance, then this could possibly be more evidence that Ben is "one of the good guys". Or, that Ben pulled something over on him. Time will tell.
