There is only one Tree Hill, and it's your home.
— Karen Roe
Karen Roe became pregnant with Dan Scott’s child when she was 17. After Dan abandoned her to take a basketball scholarship to college, where he met Deb Lee and fathered his child with her (Nathan Scott), Karen raised their son Lucas Scott alone, although Keith, Dan's older brother, took over the role of father figure. Karen also started her own business: Karen's Café.
Karen and her son Lucas are very close and she has always been supportive of his dreams. She was the one to push him to play basketball, for instance, when the opportunity (triggered by Keith) came up. However she is always afraid of the past and is initially against Lucas joining the school basketball team as it brings him into contact with his half-brother Nathan and their father Dan. However, Karen begins to grow in confidence and let go of the past and to follow her dreams she goes to Italy to take cooking lessons, a dream she always had. She becomes good friends with Dan's wife Deb Scott, who becomes a partner in Karen's Café. She also grows ever closer to Keith Scott. It seems certain that Karen and Keith are going to become romantically involved after she kisses him before she leaves to go to Italy, but on the night of her return, she finds Lucas on the brink of death due to a car crash caused by Keith's drunk driving. This drives the couple apart for a long time as she feels she trusted Keith with the one person she loved the most and he let her down. Karen is grateful to Dan for pulling Lucas from the car and giving consent for the doctors to operate on him, and on seeing Dan for the first time since the accident she hugs him, although they soon become hostile again. While Lucas is in the hospital Karen meets his girlfriend Brooke, and after a shaky start they find they have a lot in common. Karen, like Brooke, was Prom Queen and captain of the cheerleaders. When Lucas tells Karen that Brooke is pregnant, Karen slaps her son, feeling that history is repeating itself. However, it turns out that Brooke in not pregnant after all. Karen begins seeing Larry Sawyer after they meet on a school trip, causing Keith to become very jealous. In a moment of desperation Keith proposes to Karen, but she declines. As a result of this Keith decides that there is nothing for him in Tree Hill and he wants to leave. Unfortunately for Karen, Lucas feels the same. He doesn't like the person he is becoming and wants to make a fresh start, by leaving Tree Hill with Keith. Karen reluctantly lets him go at the end of the season, stating that there is only one Tree Hill and it is his home.
Although Lucas soon returns to Tree Hill, Karen decides to go to college to obtain a qualification in business, and she falls in love with her younger business teacher, Andy Hargrove. She also opens the TRIC nightclub with Deb and Peyton, which offers alcohol-free parties for the underage. Dan, however, won't let Karen be happy and manages to get Andy fired and Lucas to move in with him. This leads Karen to investigate him, to discover anything she can use to get her son back. She discovers that Dan hired Keith's new girlfriend Jules to break his heart. Karen confronts Jules, which leads to her leaving Keith at the altar. Keith then leaves town, leaving Karen worried about him. While Lucas is living with Dan, Brooke needs a place to stay and Karen offers to take her in. They become close and Karen becomes the only real mother figure in Brooke's life, as Brooke's biological mother doesn't seem to care about her. Andy meanwhile is forced to leave the country as Dan is having him deported. When Karen confronts Dan, he grabs and kisses her before laughing at her. Enraged, Karen throws a chair through Dan's office window. At the end of the season, Lucas moves back home and Karen goes to visit Andy in New Zealand.
Karen is one of the many people suspected by Dan of starting the fire at the dealership that nearly killed him. When Dan finds evidence which points towards Keith as the firestarter, Karen calls Keith and he returns to Tree Hill. Karen and Keith finally begin dating and become engaged. Keith also makes plans to adopt Lucas. Keith and Karen's happiness is short-lived, however, when just days after getting engaged, Keith is secretly killed by Dan (who blames the murder on Jimmy Edwards, a Tree Hill High student holding kids hostage in the school). Karen goes through a period of shock where she doesn't talk to anyone, even her own son. She even blames Lucas for Keith's death when she finds out that Lucas saved Dan in the fire, saying that if Lucas hadn't tried to be a hero and gone back in that school then Keith wouldn't have been killed. She also blames Dan for letting Keith go into the school and smashes up his office, unaware just how responsible Dan is. Karen gets past her grief when Lucas tells her about his heart condition, which he has spent months hiding from her. At Keith's grave, she reveals to Dan that she is pregnant with Keith's baby. Dan then holds her in his arms and promises to be there for her this time.
Karen breaks off her partnership with Deb when she finds out that she took a gun to her Café and is back on pills. Deb, who was the legal owner of TRIC, then fires Karen from the club, although she is eventually forced by Dan to sign the club over to Karen. Karen and Dan get closer as he tries to make up for killing his brother by helping her with her pregnancy, but Karen does not know he killed Keith. Lucas finds out that it was Dan and tells Karen. The distress causes Karen to collapse. Karen has to have an emergency c-section, resulting in a healthy baby girl, Lily Roe Scott. With Deb by her side, Karen flatlines and dreams of being with Keith and Lily. Karen recovers and confronts Dan in prison, lamenting that she'll one day have to explain to Lily why her father isn't there: because he was killed by the little brother he loved so much. Karen is then left to raise Lily, with Lucas at her side.
Four years since the events of season four, Karen has been traveling the world with Lily, and it is unclear as to whether Andy has been with her whilst she has traveled. She returns to Tree Hill on the day of Lucas's wedding to Lindsay with Andy and Lily in town. With the ceremony only a few hours away, Karen uses the little time she had to visit Keith's grave where she lays flowers to remember her one true love. Then, at her former Café, which is now Clothes Over Bros, she offers Brooke and Peyton advice on how their lives will turn out. When Dan appears at Haley and Nathan's house, Karen looks shocked to see him.
