Story of the character Edit

Life before Season 1 Edit

Kirsten dated Jimmy Cooper during high school but broke up with him when she was admitted to the University of California, Berkeley--at least, that was her excuse for the break-up. The truth was that she was pregnant but she decided to abort (a secret she never revealed to Jimmy, but instead revealed it to Sandy, but only years later when she was pregnant with Sophie).

Season 1 Edit

During the first season, Kirsten has to deal with suddenly having another child: Ryan Atwood. At first she steadfastly resists having Ryan stay in the Cohen house, but in the third episode, she and Seth rescue Ryan from juvenile detention. After Ryan's biological mother, Dawn, embarrasses herself, her son and everyone else at a society event, Kirsten and Sandy agree to officially adopt Ryan.

Kirsten also plays a large role in her father's business. She is very successful, and on numerous occasions this causes Sandy to feel a little insecure.

Season 2 Edit

Her true problems began during the second season when she fears that her husband is "cheating" on her with his old fianceé, Rebecca Bloom. Sandy and Kirsten's marriage begins to deteriorate, and she turns to alcohol to compensate. Her alcoholism is fueled by working closely with Carter Buckley, whom she has a crush on.

While Sandy is away with the boys in Miami, she invites Carter over and they share a passionate kiss before he decides to leave town. After Carter leaves, Kirsten's drinking problem becomes worse. She drives drunk and gets into a severe car accident, which leaves her undamaged.

When her father, Caleb, tries to talk to her about her drinking issue, Kirsten says extremely rude things. This is the last time she sees her father; he dies later that night when he suffers a heart attack and drowns in the pool at his mansion.

At Caleb's funeral, Kirsten makes a scene by drinking far too much and screaming at Sandy in the middle of the reception. After an intervention from her family and friends, she goes to rehab.

Season 3 Edit

Thanks to the support of the Cohens and their friends, slowly, she is returning to being the old Kiki, the one, who didn't need to stick to the bottle to feel good.

Fortunately, Charlotte fails in intent, thanks to the intervention of Julie Cooper, then Charlotte leaves.
