Synopsis
On night shift in the Emergency Department, Henrik Hanssen gives the team a pep-talk about improving the department. But they have no idea what’s in store for them that evening.

Iain and Dixie arrive at a tattoo parlour only to find a distraught Bonnie and her boyfriend Clyde bleeding on the floor from what appears to be a gunshot wound to the chest. Bonnie hands Iain an envelope - a suicide note. Upon his arrival at the Emergency Department, Ethan wants to resuscitate Clyde, but Hanssen reminds him that he can’t. Knowing that Ethan won’t let Clyde die, Bonnie makes out that she and Ethan have a relationship, in front of Hanssen - hoping Ethan will be taken off the case.

Ethan is suspicious that she was the one who pulled the trigger and killed her boyfriend Clyde. He later discovers that she did in fact kill him, but he doesn't realise that she has drugged his coffee. By the time he manages to report it to the police, she has boarded a plane.
