After Knight Rider ended, there were 4 scripts that were never produced into actual episodes. I believe season 4 was cut short when it was cancelled. The name of one of those scripts was "Blood Bay." Unfortunately, I don't have access to that script, so this is an interpretation of what that episode could have been. Written with my very good friend Charlie Edwards.
I have always loved "In the Air Tonight" by Phil Collins. no copyright infringement intended. This short story is about how Michael still suffers from Tanya Walker's betrayal and how Kitt helps him deal with that and just their friendship in general. I hope you enjoy this one, I think it turned out well.
