Gemma "Gem" Dean is a Porter in the Emergency Department and the younger sister of paramedic Iain Dean.


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.[1]


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.
