During Gemma's childhood, Iain went off to Afghanistan with the army. She didn't see him thereafter until 2017, when she recognised him as a paramedic. Afterwards Gem got a job at the ED as a barista. That April, she handed herself into the police after her car accident involving Lily, therefore distancing herself from Iain once more.
After a considerable amount of months, Gemma Dean returned to the ED to work as a porter where she met Rashid "Rash" Masum. In Series 33, Rash and Gemma have gone into a relationship. As of 31st March 2018, Gem is the only known porter working in the Emergency Department.
