<P> A Human owned by the Ash as his property, she serves as a doctor and scientist for the Light Fae . She was seduced by Bo during their first meeting and hence fell in love with her . She has extensive knowledge of the different types of Fae and their abilities . In the first season, she helped Bo learn how to control her powers so that she could have sex with both Fae and humans without hurting or killing them . It is later revealed that she had a human girlfriend, Nadia, who had fallen into a coma five years earlier after contracting a mysterious virus while in the Congo with her . In exchange for her servitude, The Ash offered Lauren access to the Light Fae's laboratory and resources to find a cure for Nadia's condition . Lauren learned from Lachlan in "Masks" that she was tricked by the previous Ash: he ordered a Dark Fae Shaman to curse Nadia into a coma to insure that Lauren would do everything in her power to find an antidote to the fever that was killing Fae, and then pulled her into the Light clan's fold . After Bo (unbeknownst to Lauren) removed the curse, Lauren and Nadia reunited; but their relationship was soon shattered when it was revealed that Nadia had been infected by the Garuda and he could control her mind and body . Bo was forced to kill Nadia when she threatened Lauren's life leaving Lauren devastated . Grieving, Lauren seeks comfort in Bo and the two grow closer emotionally . In the Season 2 finale, Lauren relinquishes her chance for freedom from the Light Fae to stay with Bo, despite encouragement from Dyson to leave while she can . </P> <P> In "Caged Fae", Bo asks Lauren to be together in a committed relationship . However, in "Delinquents", Tamsin visits Lauren to furtively carry out one of her mercenary tasks, and intentionally provokes Lauren by telling her that she and Bo kissed without Bo feeding from her (not knowing that the kiss was caused by Trick and Stella touching the Dawning invitation machine at the moment they shared a first kiss in "Fae - ge Against The Machine", which made the machine spark, and propelled Tamsin towards Bo to kiss her). Overwhelmed by the all the stress and loss she had experienced, and feeling inadequate in satisfying Bo's succubus nature, Lauren tells Bo that she needs to take a "break" from the relationship . As time passes, however, Bo becomes concerned that it might not be a temporary separation . In "Adventures In Fae - bysitting", a part of Lauren's past is disclosed and we learn that her real name is Karen Beattie and that she is a fugitive wanted by the International Criminal Offences and Criminal Intelligence Bureau . In addition to English she is also fluent in Spanish, French and Swahili . In "Those Who Wander" Lauren feigns being through with Bo in the presence of Dr. Isaac Taft and rejects her to protect Bo, and herself, from him . After this encounter, Bo and Lauren go their separate ways . Lauren then sabotages Taft's plan to extract Dyson's DNA and transfer the cells into him so as to become a Wolf - Shapeshifter, and turns Taft into a human / Cabbit hybrid instead, making him an easy kill for Dyson . She goes missing thereafter . (The conversation that she and Dyson had during a phone call in "Sleeping Beauty School" showed that Dyson was aware of Lauren's motives for subjecting him to the deceptive procedure .) In "Turn to Stone", Lauren reveals to Crystal that she has a brother, they had been inseparable, and decided together "to change the world", but their cause had turned into blowing up pipelines . Lauren knew how to build pipe bombs and made them for her brother to position; however, one location was supposed to have been deserted but wasn't, and eleven people were killed in the explosion . This led Lauren (Karen Beattie) to go on the run, change her identity, and keep running ever since . Lauren confesses that not a day goes by that she doesn't hate herself for what happened . (By the details in the ICOCIB wanted poster, the incident occurred in 1998, when Lauren was 17 or 18 years old .) In "Let the Dark Times Roll", Bo and Lauren are reunited at a Dark Fae party after the passage of a month, during which Lauren's memory of Bo was removed by The Wanderer . They jump into each other's arms and kiss passionately . Lauren told Bo that she had fled for her life after the Una Mens began to kill humans . The Dark Fae (i.e. The Morrigan) came looking for her, offering refuge, protection, and freedom to come and go as she pleased in exchange for working for the clan . When Bo tells Lauren that she can offer her protection by claiming her, Lauren turns her down . After being owned by The Ash for over five years, Lauren doesn't want to be owned by anyone, even Bo . Bo walks away, stunned and bewildered by Lauren's response . In "Dark Horse", Bo and Lauren reconciled after Bo saved Lauren from Massimo . Lauren saw that Bo was wearing the necklace gift from Lauren she had found in "Turn to Stone". When a defiant Lauren tells Bo that she's not afraid of the Fae, Bo admiringly told her, "You really are Dark"; to which Lauren replied, "No, Bo . I'm yours ." Bo starts to leave, but turns around and walks back to Lauren and kisses her . </P> <P> At the start of Season 5, Bo and Lauren have remained good friends, putting behind their previous tensions . In Big in Japan, when Bo felt that she was alone, following Kenzi's departure, Lauren was among those who reassured Bo that she would never be alone, because she stole her heart . In Here Comes the Night, Bo and Lauren made love again since their breakup in Season 3 . They were seen by Tamsin, who had initiated a sexual relationship with Bo and thought the two were now "girlfriends". When Bo realized their' friends with benefits' had been misunderstood she told Tamsin that she did love her, but not in a romantic way . In "End of Faes", Tamsin told Bo that it didn't matter where her body was, because her heart will always be with Lauren; that she and Lauren will always be a couple, even when they were not . Afterwards, Bo stopped Lauren to talk about what happened between them the day before and told her, "There's always going to be a reason for us not to be together . And I don't want to put this off any longer ." Bewildered, Lauren simply says, "Oh, Boy ." Bo asks, "' Oh, Boy', No . Or' Oh, Boy', Yes?" Tamsin later tells Lauren that she and Bo should get back together . Tamsin told Lauren "I entered the game and I lost . That's life . The best woman won . I'm over it . You should be, too ." Later, Bo, Lauren and Dyson are searching for Mark, Dyson's son . Bo had to leave to find one of the Ancient Fae, Iris, while Lauren and Dyson search for Mark, but before they went different ways, Lauren tells Bo, "Oh, Boy, Yes"; letting her know that she, too, wanted to resume their relationship . In "Rise", as the series comes to an end, Lauren tells Bo that she wants to spend the rest of her life with her, acknowledging mistakes that she would never make again . Both admit their relationship is messy and complicated, but after Lauren assures Bo that she is willing to weather the inevitable complications of their lives, Bo, gladdened, accepts her proposal . They embrace and kiss, this time forever . </P> <P> The bartender and owner of the only Fae pub in town, The Dal Riata, which is neutral ground where Light and Dark Fae can freely socialize and find sanctuary . Trick is very powerful: he is a Blood Sage and can alter fate by writing it with his blood . Once known as the Blood King, he forced the truce and wrote the decrees that ended the war between Light and Dark Fae; and though few are now aware of his former position in the Fae hierarchy, he is on equal terms with the Fae Elders . Compared to other Fae, who have contempt for humans, he is tolerant and often fond of humans, even trading away his most prized possession to help save Kenzi's life after she was infected with a lethal Fae virus . He respects Lauren and when necessary seeks her opinion and expertise with matters involving Fae . Trick is extremely reluctant to use his blood powers as it can have unforeseen consequences; for example, his writing a culmination where Aife's maternal instincts emerge and stop her from hurting and killing Bo not only left him weakened and wounded from the loss of blood, but also signaled his whereabouts to an ancient enemy of the Fae, the Garuda . Near the end of the second season, it was revealed that Trick is Bo's maternal grandfather . </P>
