I wonder if she knows it. She's pretty young and starstruck. He's looked long and hard to find some young thing that would serve that purpose. He is Scientology's mouthpiece. If it's such a 'normal' and good thing, why does he always, despite his wealth and status, seem to be working soooo hard to appear 'normal'. Rhetorical, really. It's because he's not and Scientology has become his dark master.
Just for posterity, I must mention Mr. Cruise's track record...I guess Katie thinks he'll change just because of her? Nope. He's asking HER to change her whole life for him, but I'm guessing he hasn't analyzed any of his numerous relationships and why they haven't worked. She should do a little demanding as well. Like--get some psychotherapy and figure out why you fail in all your relationships. I know...THE CULT won't let him get psychotherapy.
RED FLAGS, KATIE! RED FLAGS!
