Yeah, Aayla didn't do so hot talking her way on the trip and her gig was pretty much up the instant she appeared.  She's getting desperate as the more she sees, the more she wants to know.  The only problem?  Harry is having nothing of it.  In true Jedi fashion, Aayla turns to the Force for guidance and actually gets some.  Now she is certain to stick her place on the ship.  After all, what could be more persuasive to the child of prophecy than a vision?
