But I don't really blame the Derrick guy, citing the fact that he never knew he was dealing with a nutcase. The supposed one night stand turned out to be a case of personal vendetta for the other party involved; Derrick even made light of the situation to her but she couldn't get the humor. solely, because she was out to make him a scapegoat- i believe he said, "what happens in Vegas stays in Vegas." Clearly, this is a vivid display of transfer of aggression. She has been locked out from the life of her child by her husband and she decides to wreck another just to make a case that she's not one to be joked with. Our choices play a vital role in who we turn out to be in life.
