Introduced as an established corporal, Georgie's storylines in the series have included her romances with Elvis Harte (Luke Pasqualino), Jaime Cole (Royce Pierreson), and Captain James (Ben Aldridge), being kept as a prisoner of war by Al-Shabaab, and her struggles and responsibilities as an army medic, both physically and mentally.

Keegan was interested in and found inspiration for her portrayal from the accounts of female combat medics that she listened to while preparing for the part.

Despite the character and her storylines being met with mixed reception, Keegan won a TV Choice award for Best Actress, alongside receiving several other nominations for her portrayal.

After accepting an offer to join 2-Section on a humanitarian mission in Kenya due to the team needing a medic, Georgie is abducted by Al-Shabaab and kept as a prisoner of war.

Once the special forces are brought in to help with her rescue, Georgie fashions an infrared signal using a TV remote, which alerts 2-Section to her location, and they plan an airstrike on the compound.

Intel suggests that Abu escaped the air strike in Kenya, and it is theorised that his associates will carry out a series of coordinated terrorist attacks across Manchester.

When 2-Section is deployed on a humanitarian mission in Nepal following an earthquake, Georgie, now a corporal, is tasked with mentoring new recruit Maisie Richards (Shalom Brune-Franklin).

After a successful rescue mission, new intel arrives, and 2-Section will be working with the special forces in Afghanistan to apprehend a Taliban leader.

Due to Georgie's emotional struggles, her commanding officer Captain James (Ben Aldridge) leaves a negative report about her.

As Captain James's health worsens, he confesses his marital struggles to Georgie and tells her about his wife, Molly Dawes (Lacey Turner), wanting a divorce.

In September 2014, it was announced that Lacey Turner, who played protagonist Molly Dawes in the first series of Our Girl, had departed from the show to return to her role on EastEnders.

As the series progresses, it is established that Georgie met Elvis on the front lines during the War in Afghanistan and Jamie in Manchester Hospital while doing a medical placement.
