Dexter (episode)
Dexter is contacted by his foster sister Debra (Jennifer Carpenter), a vice officer in the Miami Metro Police Department. Dexter, a blood spatter analyst for the department, assists Debra in investigating an apparent serial killer targeting prostitutes. Dexter examines the latest victim and is shocked to find no trace of blood on the dismembered corpse. At the police station, Dexter discusses another murder case being handled by James Doakes (Erik King), a detective who dislikes him. Later, Dexter watches Jamie Jaworski, a murderer who escaped justice due to a faulty warrant, and breaks into his home to find evidence. Once he confirms that Jaworski is guilty, Dexter meets with his girlfriend Rita Bennett (Julie Benz), a former victim of domestic abuse victim; Rita has two young children, Astor and Cody. While on a date with Rita, Dexter finds another murder scene with no traces of blood, this time with the victim's head missing. Dexter theorizes that the killer murders his victims in extreme cold, explaining the absence of blood, and might be using a stolen refrigerated truck. Dexter allows Debra to pitch the theory, but their superior officer, Lt. María LaGuerta (Lauren Vélez), dismisses it.
List of Dexter characters
Joe and Dexter, when compared, are shown to have great physical resemblance, and Dexter also inherited his father's bowling skill.Gail Brandon is Rita's mother, Astor, Cody and Harrison's grandmother and Dexter's mother-in-law. Gail is a former public-school teacher who was fired by the school board due to "philosophical disagreements" (she disapproved of what she saw as the gradual acceptance of mediocrity in the way schools treated children and made her feelings well-known). She has extremely high standards, making her judgmental of her daughter and her grandchildren. After she arrives, she becomes suspicious of Dexter, claiming that he is hiding something. She distrusts Dexter, and believes him to be a drug addict, and believes Rita is repeating her mistake with Paul by getting involved with another addict. Near the end of Season 2, her attitude causes Rita to break off her ties with her mother and force her to leave her home and return to Michigan, not wanting her children to be exposed to her the way she was. In Season 3, Gail refused to attend Dexter and Rita's wedding, claiming that because she had started teaching again she was too busy. She did, however, send a scathing card expressing her hope that Rita's third marriage would be "the charm", though Rita is hiding that fact in stating that her mother means the third child (it is also revealed that her surname, and therefore Rita's maiden name, is "Brandon").Paul Bennett is Rita's abusive and manipulative ex-husband and the father of Astor and Cody. After his release from prison, to which he was sentenced for nearly beating Rita to death, he tries to rekindle a relationship with his children, though he still harbors disdain for Rita. Paul (correctly) suspects Dexter of framing him for the drug charge that sent him to his latest stint in jail. After a short while in a federal prison, he loses hope after failing to convince Rita of Dexter's plan to frame him. Rita later tells Dexter that he provoked a fight shortly thereafter with another inmate, who beat him to death with a pipe.
