Selena and Nathan are back together, but she wants to keep it from her colleagues. Nathan tries to undermine Harry by offering him a position which he would share with Selena. This plan backfires when it brings the friends closer together, which makes Nathan jealous.
Meanwhile, a new no-smoking policy on hospital premises for staff puts Kelsey in a bad mood. She cheers up when Alice has an idea for a staff game. Elsewhere, the rota for the paramedics has been changed behind Josh's back so that Dixie and Cyd are back in a team together. Josh is unimpressed by the effort to undermine him and partners Cyd with himself. Over the course of the day the relationship between Dixie and Josh improves, and this gives Cyd and Greg a chance to talk as well.

Casualty is the world's longest running and most successful medical drama series on television. It depicts the private and working lives of the patients, doctors, nurses and all others attending a small but frantically busy accident and emergency department of the large Holby General hospital. By mixing episodic plots with longer, character-based stories it ensures that we get to know the characters as people with lives, not just doctors or nurses. With consistently superb storylines and great acting, Casualty is compulsive viewing. The show began in 1986 and since then only one character remains; the one and only Charlie Fairhead played by Derek Thompson.
