Iain Dean

As Iain begins working with Jeff and Dixie, it's clear that he is extremely confident and may need to be kept in line. However, he soon gets a chance to prove his worth when the team are alerted to a terrifying bus crash.

In tense scenes, Iain manages to rescue guest character Anna just moments before there is an explosion on the wrecked vehicle.

Later, however, Iain finds himself in hot water with Jeff for not following instructions and endangering a patient… ,Sam, meanwhile, is shocked to see Iain at Holby. As they used to be an item, Sam can't help but wonder whether she's the reason for his arrival - especially since he seems to be jealous of Tom. Is Sam right to be concerned?

The reason Iain is very close to Sam Nicholls is that he served as Sam's Corporal in Afghanistan, and acted as comfort for Sam.

Iain returned at Jeff Collier's funeral. Tamzin left so there was only one paramedic left, Dixie. Dixie would struggle on her own, so she asked Iain if he wanted his old job back - to which he agreed.
