The Sims 2: UniversityEdit
Lauren and Amanda Lopez became close Friends after they met in Part 3: Bowling at the Student Union. Amanda would occasionally invite her over to her dormitory or for a night out. Amanda once invited she and Remington on a disastrous night out in Downtown Pleasantview.
In Part 6: Spring Break, Amanda took Lauren on a vacation to Twikkii Island. Lifesimmer calls Lauren a "boring" companion because she was not very interactive and could often be seen wandering around on her own. Amanda spontaneously kissed Lauren, and, due to their strong friendship, they fell in love. Amanda and Lauren never performed any more romantic interactions after returning to university.
Lauren was one of the guests whom attended Amanda's graduation party, where she cheated on Amanda with the evil mascot Nicholas Okuma. This caused Amanda to be furious with her.
The Sims 2: All in One Edit
Amanda invited Lauren out shopping in Part 6: DENIED! Lauren still wears her cap and gown as she attended Amanda's graduation but never Aged Up herself. She makes her second appearance of the season in Part 20: Quick Clubbin', when Amanda invited her to a night out in Downtown Pleasantview. Lauren appears somewhat uninterested by this point and it seems her friendship with Amanda has weakened.
In Part 26: Blabber, Lauren aged up off-camera and became an Elder.
