Is everyone speculating that Ben will send Sayid after Penny? I don't think he will. Sayid is working with/for Ben, taking out the bad guys. But that doesn't mean that Ben has to have Sayid kill everyone that he wants dead. This is pretty personal for Ben, he told Charles 'I'm going to kill your daughter'. Of course this doesn't have to be literal, he could have her killed but I just don't see him going to all the trouble of manipulating Sayid into doing it.
