Kristina is a regular teenager that is growing up in the town of Reno. Before she goes to visit her dad in Albuquerque she was a good student and had a few really close friends. While visiting her dad tho she met Adam, a boy that she took interest in when she first seen him. Adam is well known in Albuquerque for drugs and so is Kristina's dad. Adam introduced Kristina to weed and she enjoyed it, but not as much as she enjoyed crank for the first time. She was at the bowling ally that her dad worked at with Adam when they agreed to get high. When Kristina returned home she returned with a split personality, Kristina was the good girl that did what she was told and Bree was the bad half of her that wanted the drugs, the experimenter.
When Kristina returned home she was a different person. Kristina was at her step dads company picnic when she met Brenden and Chase. Brenden was a lifeguard at the water park and Chase is the school bully. They were both into drugs and Kristina liked that about them. Brenden and Chase would take Kristina out to parties, drive her to school and buy her the drugs. Kristina became very attached to these two boys and was hardly thinking about Adam. Brenden would take things to far tho one night when Kristina and him were on a moonlight date in the Field just off the side of an abandoned road outside of town. Kristina and Brenden were getting high and Brenden started taking her clothes off and she said stop but he didn't.
After the incident she met Trent's sister Robyn who also smoked up and they two of them became really close friends. Kristina would pick up off of Robyn whenever she needed. Kristina was no longer a good student she spent all her free time smoking cigarettes and getting high nothing else really mattered. Kristina was also taking it out on her family sometimes. Causing fights and arguing which she never did before she went to her dads.
