Plot
New ED consultant Elle Gardner is running late for her first shift at Holby City hospital. She rushes to the car and, while on the way to the hospital, is held up in traffic. Not wanting to be late, Elle decides to drive through the park, but accidentally hits Vince Callaghan, who is also making his way to the ED. Elle calls for an ambulance for Vince, and travels alongside paramedics Iain Dean and Jez Andrews to the ED.Upon arriving at the ED, Vince jumps out of the ambulance and runs to Shelle Jones, who takes Vince into an empty pub just around the corner from the hospital. Elle, and consultant Zoe Hanna, follow Vince and Shelle into the pub, and become embroiled in an argument between the pair. Shelle pulls a knife from her pocket and slashes Vince across the arm, severing an artery. Vince falls back and smashes his head against a slot machine. Shelle then targets Elle and Zoe, holding them hostage alongside Vince in the storage room of the pub.
Meanwhile, patient Mercedes Christie raises her concerns of not being able to contact Vince, her partner, to porter Max Walker. Max asks if anyone has seen Zoe, who is also his partner. Consultant Dylan Keogh reveals he saw Zoe heading for the pub. Max goes over to the pub to investigate, and upon entering the pub, he overhears Shelle shouting in the storage room. He opens the door to the storage room and is almost attacked by a knife-wielding Shelle. Zoe punches Shelle and is stabbed in the hand. The police are called and Shelle is arrested.
Following the hostage ordeal, Zoe returns to the ED, and whilst having her hand treated by Dylan, tells him that she is leaving the hospital in a few hours for Michigan to work for former consultant Nick Jordan. Max tells Zoe he is planning to move to America with her, but Zoe sneaks away from the hospital in a taxi to the airport before he can join her. Upon learning she has run away, Max drives to the airport, where he finds Zoe, who tells him their relationship has come to an end, leaving him heartbroken.
