Leah learned she was pregnant with hubby Robbie's baby. Robin revealed that she was having an affair with Robbie, which caused Leah to miscarry. Leah forgave her husband and they reunited. Robin faked a pregnancy to try to hold on to Robbie, but Sofia revealed the truth.
Leah then learned a shocking secret: her and Robin are half sisters! The two started to bond and grow closer, after Leah forgave Robin for sleeping with Robbie.
Leah then discovered Natasha was alive at the Calimo cabin with Shane. She helped bring Natasha home. She also discovered that Rebecca and Robin were half sisters, and brought them together. Leah was at work one day when she got a blast from her past: Jeff Claus, her ex husband returned. He revealed that they were still married and his parents lied to her about their baby. Jeff's parents did not approve of Leah and when she was giving birth, they lied to her and told her that their baby had died. In fact, Noah was alive and 10 years old! A DNA proved Jeff's story was correct. Leah reunited with her son. Jeff finally agreed to annul his marriage to Leah. She and Robbie married. Tension between Leah and Jeff grew as they struggled to share Noah. A drunken Meggan hit Noah with her car; he died of his injuries.
Leah was devastated and turned to Jeff for support, creating conflict with Robbie who felt like Leah was not leaning on him. The couple continued to drift apart and Leah shared some secret kisses with Jeff. At Meggan’s homecoming party, Leah learned that Meggan killed Noah. She attacked her. Robbie was horrified at his wife’s behaviour. Leah was thrilled when Meggan was arrested. She and Jeff planned to rally to advocate the death penalty in Meggan’s case. On Christmas, she reached out to Robbie.
Their union was short lived as he learned her plans for Meggan’s case. She and Jeff did rally for the death sentence; at the trial however Meggan was found guilty and sentenced to twenty years in jail. At the same time, Leah began coughing up blood. After the trial, she collapsed and was rushed to the ER. Her family and friends learned that her kidney was failing and she would need a transplant to survive. Meggan, of all people, was able to donate. Jeff agreed to have Meggan released from jail to donate; she did and Leah got better. Afterwards, she and Robbie struggled to put their marriage back together as he was upset that she shut him out for so long. After a fight with Robbie, Leah slipped into bed with Jeff. Afterwards, she felt terrible and told Jeff that they shouldn't have and that it was over. Jeff was crushed. Leah, meanwhile, reunited with Robbie and told him she wanted to start a family with him. She discovered that she was pregnant and feared about who the baby's father was. She went to Dominick and he arranged for a paternity test. Leah went, but unbeknownst to her, Dominick paid off the doctor not to do the test. Dominick told his daughter that Robbie was the father of the baby, knowing that she what she wanted to hear. Leah rejoyced. She saw Jeff with Madeline and felt jealousy, however. Robbie was shot on New Years Eve.
While Robbie was near death, Leah started to worry that she would lose her husband and her baby would grow up without a father. Dominick returned to Liam, the doctor that performed the paternity test and learned the truth: Jeff is the father of Leah's baby! Leah was stunned and never told anyone. Robbie pulled through and Leah found it increasingly hard to keep the truth from her husband and friends. Robbie was released from the hospital and the new family grew closer. Jeff, meanwhile, realized that Leah would never leave her husband. He say goodbye to her and left town. Leah breathed a sigh of relief, until Robin started dating Liam!
In the wake of Sofia's death, Leah supported Robbie with the loss of his mother. She encouraged him to lean on her, which he did. They bonded as a family with Paige. Dominick, meanwhile, started his own company and asked Leah to join his company. She said no claiming she needed to support her husband and Bob right now in their time of need. As Robin continued to date Liam, Leah became increasingly worried that Liam would reveal Paige's paternity. She visited the doctor and he told her he would never say anything. Madeline, meanwhile, spotted Leah and Liam agruing and wondered what they were fighting about. Little did Leah know, Madeline discovered her secret: Paige is really Jeff's daughter, not Robbie's! Bob, meanwhile sent Leah to Boston on a business trip to hire a new chemist. Leah unexpectedly ran into Jeff and they caught up. When she got home, she couldn't stop thinking about her ex-husband. To her surprise, Bob hired Jeff and he started to work with her. Leah was put off when Jeff announced that he was dating Veronica Lane, the new chemist that she hired. Robin, meanwhile, confronted Leah about Paige's paternity. Leah tearfully admitted it to her, telling her sister that no one could ever learn the truth. On New Years, Leah overheard Jeff proporse to Veronica.
Leah and Jeff continued to grow closer at Roboto while working on the new launch. Her marriage to Robbie became more stranged as a result. On the anniversay of Noah's death, she and Jeff shared a kiss unaware that Madeline had witnessed it. On the day of Robin and Cory's wedding, Leah and Robbie vowed to reconnect with each other and decided to renew their vows as well. Too bad Madeline decided to reveal her secret: she sent Jeff a note telling him that Paige is really his daughter, not Robbie's! Jeff stopped the wedding and demanded to know the truth. Robbie defended Leah, but when Jeff demanded a paternity test Leah finally admitted the truth. Robbie walked out on his wife leaving her devastated and left Jeff with a daughter he never knew about. In the wake of the truth coming out, Jeff asked Leah if he could spend time with Paige. Leah was apprehensive, but agreed. She confessed to Dominick that she felt like everyone hated her for the lies. He told her to be strong. Robbie finally confronted his wife and they had a huge fight. He revealed that he slept with Victoria; Leah was crushed. He also told her he wanted a divorce. Leah was upset but started to wonder why she and Jeff were always being pulled back together. She realized that she was in love with him so she stopped his wedding to Veronica. Veronica grew fed up with Jeff; dumped him and left town. Leah and Jeff made love.
Jeff proposed to Leah in the New Year and she happily accepted. She quit working at Roboto soon after and went to work for her father at Robertson Enterprises. Robbie, meanwhile, learned of Leah's quick engagement to Jeff and sued her for custody of Paige! Leah was devastated by the turn of events but she was relieved when she won custody of Paige. Dominick had been supporting her through out the trial and she noticed that he disappeared near the end of the trial. She and Jeff celebrated winning Paige and got engaged soon after. Dominick returned home; Leah pressed him for information as to his whereabouts but he claimed he was on a business trip. Leah and Jeff started to plan their wedding, during which Leah confessed to him that she missed her mother, who passed away when Leah was younger. On the day of the wedding, Bob stopped the ceremony with a shocker: Felicia Robertson is alive and well! Turns out, Felicia was mentally ill and instead of having his family watch Felicia slowly get worse, he faked her death and put her in a mental facility in Switzerland. Devastated by his betrayal, Leah slapped her father and took Felicia back to her house. She started putting all of her energy into Felicia, who continued to have to be on her medication. Jeff started to feel left out as Leah put off their wedding until Felicia was more stable.
Leah and Jeff continued to butt heads over Felicia living with them as she wanted her mother close to her. Jeff continued to press his fiance to let Felicia move out so they can move on with their lives. Leah did agree, however, to send Paige to Europe until Felicia was on more stable grounds. After Paige was gone, Jeff convinced Leah to go to Lake Tahoe to get married. When they arrived, they were surprised to see Robbie and Victoria there as well. What they didn't know, however, was that an unhinged Felicia had followed them as well. Dominick arrived and warned Leah that Felicia was in Lake Tahoe. The father/daughter made up for his role in faking Felicia's death but Leah told him she still wanted to get married to Jeff. They did by the lake. Afterwards, Jeff went to get some champagne and left Leah alone. Felicia arrived was crushed to learn that Leah had married Jeff. As she was meds, Felicia lost it. She knocked Leah out and kidnapped her. She took Leah to a near by abandoned farm house and tied her up. Leah begged her mother to let her go but Felicia refused. Leah soon smelled gas in the farm house and worried when Felicia said she was cold and wanted to start a fire. Shortly after, Felicia did start a fire and Leah worried they would die. Robbie found them and Leah begged him to get Felicia out of the house. Robbie did so ... but the house exploded while Leah was still inside!
