A third rate comedian ends up being stabbed in the men's toilet and Jimmy finds him and summons help. Valerie's faced with patient unrest over the conditions in casualty and Lucy is stressed over working conditions, as her exams loom. Duffy has doubts about Andrew's commitment and Megan tells Charlie she's overcoming her pill dependency. Jimmy's in a state of shock and the police question him over the stabbing, as Andrew attends to Arthur and has to call for the crash team to take over. Lucy tells him she wants to specialise in general surgery and congratulates him on his new job and assumes Duffy will go with him. Jimmy gives the department a shake up which amuses Valerie and Duffy carpets Alex for giving a patient some pain killers and tells her she's reporting the incident. Megan tries to find out why a woman swallowed bleach and a man with slashed wrists is brought in, refusing to talk. Charlie tells Valerie he wants Jimmy out but she's unwilling and asks why he's in a bad mood.
