Never Going to Happen
Sometimes Horatio worried his life was too perfect. Once in a blue moon he would fear that Aimee would eventually found someone younger and leave him. He wasn't worried that she would deprive him of being a dad to their girls but of losing her. When she was out with her girlfriends Aimee was often hit on, given phone numbers and bought drinks. She ignored come-ons, sent back drinks and notes, stating she were happily. It got on her nerves sometimes that some men had a hard time taking 'no' for an answer.
Twice when Aimee was approximately four months—visibly pregnant with her second child, she was out with friends celebrating a birthday and another's job promotion she was approached—by men her age who were not by any means unattractive. When Aimee told the second of the two men she was "very married" the guy replied "so? Your ol' man just left. I'm sure he's got you on short supply. You're young, you could have some fun. Your baby might even enjoy it."
Horatio had dropped Aimee off and the man must have seen him kiss Aimee before he left.
Aimee told the guy he had better turn around and walk away if he didn't want the drink she had in her hand thrown in his face. She wanted Horatio and only Horatio.
