almost becomes one of her victims when he has a heart attack and is placed in her care. Harry gives Dexter 'permission' to kill her and he ambushes her at her house. Her victims were Phoebe Burns, Jason Kheel, David Nammers among others. Dexter gives her the nickname "First Nurse" in the series, although in the novels her nickname is "Last Nurse". In the novels, the nurse is basically the same as in the TV series. However, her motivation for killing her patients is never given in the novels. In the TV series, she claims to be helping her victims by "ending their pain". She is speculated to have been inspired by prolific serial killer Harold Shipman.

She was inconvenienced by Lieutenant María LaGuerta's false accusation of her son, followed by learning of his kidnapping. María was forced to apologize to her by Captain Matthews, but she was thankful rather than displeased that she came in person. Throughout the time her son was kidnapped, she prayed almost non-stop and towards the end of the episode reminded María of her faith. Nina Batista (Angela Alvarado Rosa) is Angel's ex-wife. The couple separated some months prior to the series premiere, following Angel having an affair with another woman. Despite Angel's attempts to get Nina back, she constantly turn him down. However, as seen following Angel nearly fatal confrontation with the Ice Truck Killer, Nina
