Cave is an insanely ambitious man with completely ambiguous morals. He does whatever he wants, and doesn't take no as an answer (especially when Aperture begins to go bankrupt). He is quite fond of his secretary Caroline (as a friend) and he HATES Black Mesa, and hates Dr. Wallace Breen in particular. He also wants to kiss Breen. And they send each other hate mail through a special portal that connects their offices. And they know each other better then anyone else does. He hates Wallace.
