Nicola was a close friend of Debbie Gallagher. She appeared in Series 3 when Debbie goes on strike from running the Gallagher household. She appeared to be a very flirtatious and bubbly girl and attractive enough for Lip to curse her age. She also appeared to enjoy male attention and when two older men made some sexual remarks to her and Debbie she called them paedophiles and threatened to get her father to beat them up but when they had driven off she laughed and smiled.
Later, she called Debbie "right weird" for not fancying anyone and not wanting to perform sexual atcs with a random teenage boy.
