Lauren Fenmore, the beautiful heiress to the Fenmore Department store chain, lost her first husband, Dr. Scott Grainger, to Sheila Carter, the conniving woman who stole Lauren and Scott's newborn child Scotty, and substituted him with a black market baby, Dylan, who died a crib death. Then after Sheila's deeds were finally exposed and Lauren and Scott were reunited, Scott died of a mysterious disease. The obsessed Sheila returned, time and time again to terrorize Lauren over the years, even escaping from a prison for the criminally insane, in both Genoa City, as well as Los Angeles.
By the time Sheila arrived in Genoa City in 2005, having had plastic surgery to look exactly like Phyllis Newman, Lauren was married to attorney, Michael Baldwin, and they had a new baby together named Fenmore, whom they called "Fen". Sheila kidnapped baby Fen and Phyllis' baby, Summer, in her plot to get even with Lauren. But in the end, Lauren was the one who killed Sheila in self defense.
Many years later, Sheila's sister, Sarah Smythe, showed up with Sheila's until then unknown twenty year old twins, Daisy and Ryder Callahan to carry on her tradition. They kidnapped Lauren and held her hostage while Sarah (who had had plastic surgery to look exactly like Lauren) took Lauren's place with Michael. Lauren ended up killing Sarah in self-defense as well, but the twins escaped, promising revenge.
Six months later, Daisy returned pregnant from drugging and raping Daniel Romalotti, and had her baby, Lucy. Lauren became fearful for herself and for Fen after Daisy was only given time-served and put on parole with psychological counseling, claiming that her actions were controlled by Sarah. So Lauren made plans for Fen to stay with her son Scotty in Toronto for his protection. Daisy boldly entered Fenmore's intending to spend a gift certificate on clothes for Lucy and taunted Lauren. Lauren freaked out and pulled a gun on Daisy, and was arrested for assault with a deadly weapon. Michael came to her aid and Lauren got off with probation. Daniel ended up marrying Daisy to safeguard his daughter, Lucy.
At their celebration of Michael's new job as interim D.A., Lauren surprised him with the return of their son Fen, who had become a teenager.
Fen became friends with Summer Newman who was having a hard time accepting being the daughter of Phyllis. After an altercation with Phyllis, Summer disappeared with Fen, and they hid out in the skating rink and kissed. After they were convinced to return home, Fen was chastised by his parents and urged to not see Summer anymore.
Noah found out that Summer had been bullying Jamie the boy that Ronan had been mentoring using FacePlace name of "Brittni", and he cautioned Summer about her irresponsible actions. Summer went to Jamie and assured him that she was not "Brittni" or like the rest of the kids who picked on him. Fen accused her of faking it, but she claimed she actually liked Jamie. Summer came on to Fen again to try to get him not to rat her out to their parents, and Fen reacted by pulling away and telling her he didn’t really like her very much. But Fen jealously took over taunting Jamie using a burner-phone due to Summer and his father Michael's sudden interest in the boy. Jamie's father was arrested for a hit and run DUI, and causing an injury. Once his father went to jail, Jamie would have no one to live with, and would be headed for foster care. Hearing about this, Fen became jealous, sure that his parents would take the kid in. Later, while talking with Summer, Jamie kissed her, and Fen found out about it.
Fen's burner-phone fell out of his backpack, but Fen claimed to Michael that he had it to cover his relationship with Summer. Jamie was put in a group home, and Michael discovered Jamie had been beaten up by his roommates, but was unable to persuade a judge to intercede. Fen saw Summer hugging Jamie again over his injuries and went off on them, telling Jamie that Summer was his FacePlace stalker Brittni, causing Jamie to pack his things and disappear. Michael confided in Paul how concerned he was that Fen was heading toward becoming another Ricky or young Michael or Kevin, being so full of rage. Paul tried to reason with Fen and convince him that Michael loved and wanted to help him.
Jamie returned, having nowhere else to go. Fen agreed to back off, and Jamie agreed he wouldn't tell Michael about Fen's texts. Fen put a valuable glass box into Jamie's backpack and stole $200 out of Lauren's purse, intent on getting Jamie in trouble. When asked if he took them, Jamie felt affronted and left. Fen followed Jamie, and they fought on the roof where Jamie had been hiding out. Jamie was later found by Paul where he had fallen to a roof below. While Jamie laid in the hospital unconscious, Michael accused Fenmore of setting Jamie up, but Lauren refused to believe it. Jamie regained consciousness and was released, but he refused to tell anyone what had happened.
Jamie told Summer that she and Fen were both responsible for everything that had happened to him. Summer apologized, explaining that by bullying him as Britni she had only been trying to get back at Ronan, but now realized it was pretty dumb. Michael confronted Fen, and Fen accused Michael of choosing Jamie over Fen, saying he would never forgive him. Then after a verbal fight between Fen and Jamie, Jamie decided to press charges against Fen. Fen was arrested in his home for assault. Lauren followed him to jail and got him out on bail after he spent the night in "juvie". Both Lauren and Fen were resentful of Michael for not supporting his son. Lauren began hanging out at the Athletic Club bar with Carmine coming onto her. He took her home one night when she had too much to drink, and another night he kissed her. Fen found out about Michael's past on the Internet and threw it in his face. Michael failed to convince Fen that it was because of his own past that he didn't want Fen going down the same road. After Paul found Jamie attempting to jump from the same roof, he convinced Jamie that he could help him make things better. Jamie admitted that he had lied and had been attempting suicide that night with Fen, and the changes were dropped against Fen. Much to Fen's relief, Ronan was granted guardianship of Jamie and he moved to Washington, D.C. to live with Ronan after apologizing to the Baldwins for all the trouble he had caused them. But Fen still refused to forgive Michael, and Lauren still resented Michael for not believing in their son as she had, and moved out.
Fen went to Kevin asking to live with them, but Kevin refused and told him to go home. Fen questioned how Christine and others could forgive Michael for the things he had done to them. Kevin told Fen that people change and prove themselves worthy of forgiveness. Christine confirmed her forgiveness, telling Fen that Michael had become one of finest men she knew. Feeling remorseful, Fen confessed to Michael everything he had done to Jamie, apologized, and said he wanted to make it up to Jamie who had nearly died because of him. Michael asked Christine to become D.A., and he stepped down.
After Lauren returned home, Michael decided their reconciliation was not working and that he would move out. Fen accused him of giving up. At On The Boulevard, Fen apologized to Summer for everything he did to her and to Jamie, then came on to her, but Summer told him she only wanted to be friends. Carmine overheard and told him to go after her; that a guy like Fen had a lot to offer.
Fen admitted to Kevin that he hated to go home, afraid that he gets so angry, and has no one. Fen told Lauren that he felt that he had broken up his parent's marriage, that he loved Summer, but she couldn't stand him, and all he does is screw up. Carmine convinced Fen to apologize to Summer and ask her to the prom, which Fen did. Summer accepted, but ditched the prom, dragging Fen to a party she had set up at her mother's penthouse instead. Everyone was drinking, and they played truth or dare. As a tipsy Fen completed his dare to kiss Summer, Kyle burst in to rescue Summer after receiving a text. Phyllis, who had just moved out of Jack's, arrived at the penthouse to find Kyle punching Fen in the mouth. She sent the other kids home and called Nick, Michael, and Lauren. When some other kids found out about it, they beat Fen up. While being consoled by his new friend, Carmine, Fen disclosed Michael's attempted rape and prison past to Carmine.
After Lauren and Michael decided to give their marriage a 30-day trial, Fen went to Carmine and wondered what had happened to split them so far apart. Carmine spilled the truth, saying that Lauren just needed to come back to him instead. Unfortunately, viewers were not shown his response. Next, Fenmore graduated from high school and was given a new car by his parents. His grandmother Joanna and half-brother Scott attended, but were unseen by viewers.
With kids still bullying Fen, he ended up at a graduation party held by the kids that don't fit in, where he met a punked-out girl named Raven, and got high. The next morning, Michael found Fen passed out on their living room floor. Michael brought him around, and he lied that he had gone to a party with Summer. Fen told Michael that he got high because he saw no future for himself, and that he was always angry. Michael told him that he spent a good deal of his life like that himself, but that finally someone had loved him enough to pull him out of it, and he had changed because of Lauren.
Later Fen caught Carmine kissing Lauren, as Lauren tried to push him away. Fen pulled him off, and Lauren told Carmine to get out. Fen asked Lauren if they were having an affair, and she replied no, not anymore. But when Michael got home, Fen told him what he had seen, and Lauren explained to Michael that Carmine had just showed up and kissed her. Fen attacked Lauren for disrespecting his father by screwing around with some bartender, and wondered how Michael could even look at her since. Michael said he defended Lauren because she was his wife, he loved her, and that she deserved a chance to make things right. Fen asked, "Why bother?" and left. Fen went to Carmine and accused him of getting off by messing with people's families. Fen told him he saw through his friendship, in that he just wanted to get close to his mother. Fen left Carmine, saying he felt betrayed by everyone.
Weeks later, Fen showed up at On the Boulevard and asked Carmine if he could hook him up with some drugs. Carmine asked why Fen would come to him, and said he thought Fen was too smart to do drugs. Fen got mad and left, but Carmine later found Fen unconscious in the alley, and accompanied him in the ambulance to the hospital. Carmine called Michael and Lauren, who kicked him out of the room on their arrival. The doctor told them that Fen had ingested a powerful methamphetamine which had caused cardiovascular collapse. When Fen woke up, he told them Carmine was responsible. But from the smile on Fen's face after Michael went ballistic, it became obvious that Fen had lied so that Carmine would go to jail and be out of his parent's lives. But Carmine's lawyer, Leslie Michaelson, got him off, explaining what really had happened, and pointed out that if Carmine wanted to hurt Fen he never would have called 911. Carmine smugly walked out, and went to Crimson Lights where he sat drooling over his laptop, watching the video of him and Lauren making love. Carmine then sent the video to the GCBuzz website, and forwarded the link to Fen's phone. Fen was repulsed and showed it to Michael and Lauren. Fen met Raven and left Crimson Lights to get high, leaving Fen's cell phone behind. Then Lauren received a text from Fen asking her for help at a remote cabin. But when she arrived, she found only Carmine. Carmine got Lauren to agree to stay an hour, if he would drop the charges. But when Lauren resisted Carmine's advances and tried to leave, he took away her purse and locked the door. Carmine got rough with Lauren and tied her to a chair, so Lauren tried playing along that she really cared about him. Lauren tried to seduce him, claiming to have only returned to Michael for her son's sake. Lauren persuaded Carmine to let her loose, and stabbed him in the arm with a fork. Meanwhile at the GCPD, Kevin tracked Lauren's phone to the landfill. Fen turned up, explaining that he had lost his phone, so everyone realized that Carmine had used it to lure Lauren, but they were unable to track it because Fen had disabled the GPS. Kevin figured out that they were probably at the same remote cabin where Angelina had taken him. Kevin caused a distraction which allowed Michael to escape. Michael broke in the door of the cabin, finding Lauren gagged and tied to the bed with Carmine ready to rape her. Michael slugged Carmine who ran into wall and hit his head, knocking him out. Paul kicked in the door to find that Carmine had escaped while Michael was untying Lauren. The charges were dropped against Michael, and Fen promised to go straight, admitting to Michael and Lauren that Carmine did not buy him drugs. But he was later arrested when he was caught on camera stealing drugs from a cart when he went to the hospital to be with Summer, whose mother Phyllis was in a coma. Thanks to Paul and Christine, Fen was given no jail time if he went to rehab. A month or so later, Fen returned home on a day pass. The family enjoyed a picnic in Chancellor Park, and Fen spoke about how difficult therapy was. His doctor felt that Fen could be released in a week.
Fen got out of rehab on a pass to see his mother accept the businesswoman of the year award at a ceremony which was held at the athletic club. Carmine, who had escaped from jail, skulked around the sidelines, dressed as a cop. Gloria was the M.C. and announced a video of the highlights of Lauren's career, but the one of Lauren and Carmine in bed played instead. Fen ran out humiliated, and began kicking trash cans around in the back alley. Carmine went out to the alley and texted Lauren that he had Fen, so she snuck away to the alley. Carmine called Michael next, but Michael heard Carmine say, "No. Don’t", then heard a gunshot. Michael found a distraught Lauren standing over Carmine's dead body, Fenmore's sobriety chip and a gun on ground. Michael asked Lauren if she did it. She responded that she wished that she had. Michael, assuming that it had been Fen, shot the gun into a wall to take the rap for Fen. Detective Chavez showed up and arrested Michael, but he was suspicious of Michael and Lauren's answers and Michael's willingness to confess. Meanwhile Fen had been seen leaving the coffee house with Raven. Lauren hired Avery to represent Michael, but he was uncooperative, even after Paul confronted him about the bullet he had dug out of the wall. When Fen admitted to Lauren that he had been high and did not remember what had happened that night, she would not let him confess to free Michael. Michael was sentenced to 10 years in prison, but Fen broke into the sentencing hearing, and confessed to killing Carmine. No one believed him, and Michael was taken to Walworth prison. It was not long before someone recognized Michael as the D.A. who sent him to prison and Michael was beaten, suffering a black eye and broken ribs. Christine then arranged for him to be put in a more secure section of the prison.
Meanwhile, Fen met with Raven and bought a lot of drugs from her, then made sure that he was caught and arrested for possession with intent to sell. Fen confessed and was sentenced to 30 days in Walworth as well, somehow expecting that if he was in prison Michael would be able to admit that he was covering for Fen and be released. Running into his beaten father, they were both shocked to see each other. Michael told Fen how to stay out of harm's way, and not to admit that they even knew each other. A con named Womack began trying to befriend Fen in a threatening way, offering him drugs once he found out what Fen's crime was. When Michael tried to intervene with the Warden for Fen, he was thrown in solitary confinement. Michael then offered a deal to be put back into the general population and become an informant. Summer visited Fen in prison, and Fen shocked her with the knowledge that his dealer Raven had told him that Summer's best friend Courtney was her biggest customer. Christine and Paul worked behind the scenes getting Michael's conviction overturned. Michael protested being released and no longer there for Fen, but he was freed in time to show up at the Chancellor estate and surprise Lauren on Thanksgiving. Meanwhile with only one week left on his sentence, Fen was being ganged up on in prison by the inmates who had been imprisoned thanks to his father, the D.A. – until Womack came to his rescue. Fen was released the following week after threats from Womack that he would not be out of his reach on the outside.
Studying the Basco murder evidence day and night, Paul pondered Fen's sobriety chip which had been found on Michael. Michael told Paul that Fen had given it to him when Fen was in rehab, but Fen said he had given it to Michael the night of Carmine's murder. After Paul got the test results from the suit that Fen had worn that night showing gun residue and Carmine's blood, a warrant was issued for Fen's arrest. Fen fled, but Summer helped Michael trick Fen into returning to the GCPD, where Michael claimed that Fen was turning himself in. Fen was put under house arrest with an ankle monitor. A cake iced to say "Forget Me Not" was left at the Baldwin's door. Lauren was sure it was from Carmine, but Fenmore admitted it was likely a reminder from Womack.
Worn out at a photo shoot, Summer took some "energy pills" from fellow model Esmeralda, had a reaction, and called Fen for help. Fen came to the shoot but was tracked by his ankle monitor and arrested. Sharon discovered Summer, who had fallen down some stairs. Summer was diagnosed with congestive heart failure, and Esmeralda had to give Dr. Rayburn the drug to help save her.
Fen accepted a plea bargain, so was to be sentenced for Carmine's murder by a judge in his chambers. Lauren made a heartfelt plea in Fen's defense blaming herself for bringing Carmine into their lives and Fen's escaping to drugs. But Michael burst in at the last minute with a video of Carmine holding that day's paper and admitting that he was still alive. Christine dropped the charges and Fen was released. It turned out that Carmine had turned state's evidence against Womack, so the government had been protecting him, which was how he was able to escape and get away with everything. Once Womack was released from prison, the Baldwins were confident they would never hear from Carmine again or Womack would have him killed. Refusing to be forgotten, Lauren received a postcard from Carmine, addressed from Puerto Rico.
Outside the Delia Project Valentine's Day benefit, Fen ran into Richard Womack, who warned Fen not to tell anyone he had seen him, and to get out of there if he wanted to live. Fen left, but went to the police station and told Paul. Womack ended up pulling a gun, and holding everyone at the benefit hostage. Paul and the rest of the police arrived outside the locked ballroom. In the end, Womack was killed as he and Colin Atkinson struggled over the gun.
Fenmore began taking night classes at GCU in hopes of getting into a high profile college in the fall, aspiring to become a lawyer like his father. Fen was accepted at Arizona State University, and left Genoa City for college.
Fen returned home on a break in October 2014, looking good with a cool beard and haircut. He met Mariah Copeland, visited Summer, and met her new husband, Austin.
