That's just it, we're each applying it in our realm of experience, and since our experiences vary greatly, so do our opinions. I can only see it through my own eyes at that time - to me, if jack were that openly flirting, he would have been dead much earlier in the film. Not that my view is any more valid than yours, because they both have validity from our realm of experience. We can agree to disagree, without any hard feelings. That is what is so great about this forum, every person's view has value.
