I voted for Tempus - as Roger said, I liked his sense of humour very much. Star was fun, too, and Dr. Klein and H.G. Wells were paranoically interesting (in my opinion).
As for the other choices:
I can't remember Jack very well, and can't remember Inspector Henderson at all.
Mindy Church was annoying, to me. I don't like this Barbie type. But I recognize that she was interesting somehow, too.
Mayson was also not my type.
And Dan made me lol and wanting to strangle him at the same time.
Nice question.
See ya,
