What Hattie was seeing, though she was quite sure she could never tell Kitt, was two different species interacting. And neither of them were human. It was like being on a different planet all over again and the anthropologist in her was in absolute awe. She watched Kitt and KITT discuss morality and immorality and humans and society and it just blew her away.
On the one hand, she didn't want to make her presence known and on the other, she was afraid they knew she was there anyway. She really didn't want to be called out for hiding. Slipping around the corner, she gave a small wave.
