It is the day of the F2s' exam and all are on edge. May is given a pep talk by her father and is shocked when he hands her an envelope with the exam questions inside in order to help her along her way. The F2s are rattled when Jordan reveals that the exam will also include a day-long assessment, with Henry overseeing. As the day progresses, Lenny is disgruntled to be given a case in cubicles, while May and Yuki are given 'exciting' resus medicine. Yuki falters while treating seriously ill teenager Seb but redeems himself when he comes up with a brilliant diagnosis. However, when Yuki bravely tells a packed resus, including Seb's father, that Seb told him he no longer wants treatment, Henry orders him out. Yuki is disappointed but Henry cheers him up by saying that there's more to medicine than books. Lenny is disappointed to be stuck in cubicles and, determined to impress, orders a series of tests for a patient. However, he is distressed to realise that the tests have revealed something sinister and he tries in vain to persuade his patient to accept treatment. May initially impresses Henry when Sarah Evans is rushed to the ED having collapsed in theatre. May's confidence leads her to throw the exam paper away but it seems this is an act - she fails to chase up a test result, putting Sarah in danger. Henry is furious with her, but her day gets even worse when she realises her father and Sarah had an affair. It's the day of Harry's funeral and Jessica rejects Adam's support, insisting she wants to return to work the next week. Charlie tries to persuade Louis to face up to his parental responsibilities. Ruth finally gathers the courage to tell Jay that she loves him but it's too late - he walks away.
