Isla Reigner (born December 2020) is the daughter of Rochelle Reigner, a construction worker.
In June 2021, when a nursery was unable to take Isla, Rochelle was forced to hide Isla in a shed on a construction site. Upon discovering that the shed was scheduled to be demolished, Rochelle rushed to her daughter's aid, but she collapsed due to her poorly managed diabetes. Frank Polt, a young colleague Rochelle was training, found Isla before the shed was destroyed and brought her into Holby City Hospital's emergency department to reunite her with Rochelle. Paediatric registrar Matthew Afolami assessed Isla and found her to be unscathed, but he ultimately contacted social services. (CAS: Episode 1206)
