I believe there is someone else above Ben listening in on everything. We know that Ben is in his hospital bed when Jack comes to talk with Kate but even so Whitebeard reminds him of people listening. It seems as if Whitebeard is really on Jack and the Losties side now. Jack was wanting to tell Kate something more than what he did. I think Jack knows alot more about the whole situation now.
