Life in The Sims 3Edit
Fiona was raised by neglectful parents and ended up being her siblings' caretaker at a young age. Upon reaching young adult, Fiona received custody of all four Gallagher siblings and moved to Dragon Valley to escape her parents and provide a better life for her siblings.
She was in a very brief relationship with Riordan Mithrilen, which produced one child, Mandy Gallagher. After her birth, Riordan cut contact with Fiona and Fiona is left to raise Mandy, with the help of Lip and Ian.
