sleeps with Abe's illegitimate son Brandon Walker before she knows of his connection to her husband. In 2005, Lexie has an affair with Tek Kramer, whom she dates after her husband is presumed dead. Lexie, while not a villain, frequently engages in unethical behavior. She also tends to stick up for her father's family, the DiMeras. Both her father Stefano and her half-brother André DiMera have helped her with her problems (often using illegal means). Fearing Lexie can't bear children, Stefano arranges for her to raise Isaac (Zack), the son of Bo Brady and Hope Brady, as her biological son after a surrogate's baby is switched with Zack in the hospital. Lexie did not know this at the time, but later chooses to keep quiet about it once she finds out, even though Hope is her best friend. In 2003, Lexie gives birth to Theo Carver, her son with Abe. However, the family's happiness is short-lived when Abe is seemingly murdered by the Salem Stalker. However, it is revealed that Abe is alive and is trapped on Melaswen ("New Salem" backwards) Island, part of a plot conducted by André. Abe and Lexie reunite when he returns to Salem in 2004. Lexie has a history of antagonism with Sami Brady. They were both involved with Brandon, and Sami blackmails Lexie on a number of occasions due to Lexie's repeated adultery. Later, Sami has Lexie lie to Sami's sister, Carrie Brady, regarding her chances of having healthy children. Breaking her Hippocratic oath, Lexie is fired from Salem University Hospital. However, with Hope's help, Lexie becomes Kayla Brady's part-time private nurse and 'personal medical adviser'. In 2007, Lexie is kidnapped by André because she claims she witnessed her half-brother EJ DiMera shooting John Black. Tek Kramer is the real witness of the crime, but they cover it up because Lexie did not want her husband to find out that she is with Tek again. Shortly afterwards, Lexie and Tek are run off the road. No bodies are recovered. Lexie is later discovered in the tunnels of Salem during a Bo and Hope investigation into the long running Brady-DiMera feud. Upon her return, Lexie reunites with her husband and is reinstated by the Salem University Hospital board and eventually becomes Chief of Staff. Her new position keeps her very busy which causes marital problems. She deals with the news that Theo is autistic. In
