Orla McCool is a student at Our Lady Immaculate College.


Orla lives in Derry, Northern Ireland, during 'the troubles', with her mother Sarah, her aunt Mary, her uncle Gerry, her grandfather Joe, and her cousins, Erin and Anna. Erin and Orla are the same age and have grown up side-by-side. They are in the same class at Our Lady Immaculate College.


Orla takes many things literally, including sarcasm, and sometimes misses social cues that others can pick up on. She often remains quiet and absent within group situations. Orla can be unaware that what she says and does, are straying from the norm and may be seen as mildly offensive. She is occasionally seen breaking into people's physical boundaries, holding onto people and once stroking the head of a nun during detention. Orla doesn't care about popularity and other's opinions of her. However, she does have strong affections for those she is closest to.

Orla has a deep love of sweets and confectionery. She is constantly seen eating sweets throughout the show. She has had an obsession with 'step aerobics' and likes to 'melt stuff'.




Orla took her grandpa Joe to her school prom, as her date, saying 'he's the fella she likes the most'.


Orla's friends are Clare Devlin, Michelle Mallon, James Maguire, and Erin Quinn.
