On his way to work, Charlie's route is blocked by a long loader lorry backing into a yard but tragedy strikes when it crushes a man and he has to administer first aid. He's taken to casualty but he can't be saved and Tony Walker's being hounded by a mental patient, who's playing games with him and is threatening suicide. When he receives a phone call from him, he realises it's Wayne and the race's on to find him, but unknown to him, he's wandering round Holby, still swallowing pills. A mother brings in her young son Matthew, but he's fine and it's only when Tony recognises her as an ex-patient, the problem is revealed. He takes her to the canteen for a chat where he spots Wayne and gives chase but he eludes him as he hides in the casualty toilets. When he's found, he is in a bad way and a fight is on to save him. A girl with a nail in her foot, is treated by Beth, but when she removes it, the mother faints.
