List of Dexter characters
On a visit to his sister, Dexter and Debra both feel as if they have been drugged; just before he passes out, Dexter sees Hannah standing over him. When he later regains consciousness, Dexter begins investigating Hannah, and finds that she has changed her name and married Miles Foster (Julian Sands), a wealthy businessman. Dexter goes to see Hannah, who says that she had wanted him to kill Foster, but changed her mind after realizing she is still in love with Dexter. Foster warns him to stay away from Hannah, and has him beaten up. Dexter goes to Foster's boat to protect Hannah, but finds that she has already killed him. The two of them dispose of the body, and promise to watch out for each other. The two end up having sex and rekindle their relationship.
List of Dexter characters
She returns to her old job once the new Lieutenant, Esme Pascal, proves to be unstable (a state LaGuerta intentionally worsens by having an affair with Pascal's fiancé). When her friend and former partner and lover, James Doakes, becomes the prime suspect in the Bay Harbor Butcher case, she tries to clear his name. However, Doakes is found dead in a seemingly accidental explosion along with the body of drug dealer Jose Garza, and the case is closed. As she recovers from the trauma of Doakes' death, she leads an investigation into the murder of Oscar Prado, the brother of her ex-boyfriend, Miguel Prado. She also develops a close relationship with defense attorney Ellen Wolf, and is devastated when Wolf is found murdered. After Miguel's own murder (ostensibly at the hands of The Skinner, but in reality by Dexter), she wants to find admissible evidence to prove he killed Wolf, but Dexter is able to convince her that doing so would only hurt Miguel's family and the Cuban community, and that even then there is a high chance that nothing will be proved. Reluctantly, LaGuerta drops it.
