Claudia Brown from Primeval
Claudia Brown is played by Lucy Brown. According to the official Primeval website, Claudia Brown, (born in Oxford) joined the Civil Service after studying law at university. For two years, she was engaged to be married, but she broke it off a month before the wedding. She has had no significant relationships since. She has fallen in love with Nick Cutter after he defended her from the "flying lizards".
Much like Lester, her official role at the Home Office is unclear. Since the discovery of the first anomaly, she has worked alongside Nick Cutter and his team, acting as a liaison with the Home Office and occasionally defending Cutter's actions to Lester, and vice versa, but is often stressed out by Cutter's methods and secrets. She is not happy when she learns Cutter's missing wife Helen is alive and that he knew, since she could give them vital information. Claudia is in love with Nick Cutter with whom she shares a passionate kiss during episode 1.5. In episode 1.6, Claudia jokingly accuses Cutter of sexual harassment, noting that it is a serious offence in the civil service. She began hallucinating, seeing anomalies and Gorgonopsid throughout the Home Office.
When Cutter and Helen started to leave, she asked him not to go as she thought it was a mistake, but he assured her that it would be okay. She and Cutter then exchanged another kiss in front of Helen and the rest of the team, and rebuffed Lester's note of it being unprofessional. When Cutter returns from the past via an anomaly, Claudia has vanished and none of his colleagues have any knowledge of who she is or was, leading Cutter to believe that something he has done in the past has altered the present, eliminating Claudia's existence. The reason for her disappearance is not yet known, though probably due to the remaining Future Predators that managed to escape the Gorgonopsid. Cutter is devastated by this, describing Claudia to co-worker Abby as "important to him" and saying he cared about her. Her non-existence shakes his foundation to the core as she is the first woman he had loved in his life since the disappearance of his wife, Helen.
Claudia remained out of existence for the second series, although another woman who appears to be physically identical, Jenny Lewis, first appears in episode 2.1. At the end of episode 2.2, Cutter explains to Jenny as best he can about what could have happened to change the past. Claudia's job as Lester's assistant was changed to a man named Oliver Leek, who was revealed to be working for Helen Cutter. It was implied that Helen was responsible for Claudia being replaced by Jenny, however Helen denies it. At the end of the finale, Cutter shreds Claudia's picture (although in Series 3 it is revealed that he repaired part of it). The writers alluded to Claudia's possible return in the future, but said that they had no plans at the time to rewrite Claudia into the timeline.

That's the problem with heroic gestures. Succeed, and you look wonderful. Fail, and all you do is leave the bloody mess for everyone to clear up. [Primeval 1.2] 2007
