CSI: Miami

Detective John Hagen (Calleigh's ex boyfriend) appears at the scene and tells her they're gonna be working together in this case because of his new job (this is his first week back). He tells her he tried calling her a few times and she says it's been crazy at the lab. Meanwhile, Wolfe arrives and asks what's up. Calleigh introduces him to Hagen. Wolfe tells him he's Ray Caine's old partner and Hagen is kind of uncomfortable with his commentary but says that he was and leaves. Ryan asks Calleigh what was that all about and she says it's complicated and that he'd been I.O.D. (Injured on Duty) Ryan asked what was the problem and she says something about a bad back; Ryan says he's heard that one before. Calleigh asks him what's that supposed to mean and Ryan says nothing, but she insists that he tells her. He says that when he worked at patrol a couple of his coworkers said "bad back" to cover that the department shrink couldn't clear them. Calleigh is left speechless. The owner of the crashed plane tries to bribe H to let him take the bags of checks, but of course H tells him to leave or he'll be placed und arrest. When Calleigh finds cash she decides to head back to the lab and Hagen offers his help and she says of course, it's his investigation too. While Calleigh and Hagen are working together Hagen starts to tell her that he wanted to talk to her but Peter Elliot comes in since this is a money case. Calleigh receives him like Mr. Elliot!!! She introduces them. She tells him she found it weird she didn't see him in a counterfeit case a couple of weeks ago and he says he worked it with H and she reproaches him that he didn't even stop to say hello. He says he dropped by but she wasn't there. (Refers to S03, E14 "One Night Stand") Peter helps Calleigh and does so like his "the man" and Hagen notices and he makes faces of "I can't believe this". Calleigh leaves with Peter and tells Hagen she'll talk to him later. Calleigh finds Hagen at the lobby and says, "how's it going?" He tells he should ask her the same question. She asks what does he mean and he asks her what's with her and the Secret Service guy (Peter). She tells him that they are colleagues not that it's any of his business. He says he can make it his business. She tells him to walk away. He asks her if she's sleeping with him and she tells him the conversation is over and turns away. He pulls her by the arm and asks he what if he doesn't want it to be over. She tells him then he better remember what she does for a living. He says her name and then lets go of her arm and walks away. On the final visuals of the episode we see Calleigh walking towards a car outside the lab and Hagen overlooking. Calleigh looks at him at wipes the smile off her face and then looks back at Peter.
