Tina is in Sydney. She tries to phone Sean but there is no answer. She phones Tourist Information to find out how to get to Alice Springs, and catches a coach there. She starts asking people if they've seen Sean, showing them a photo, and is soon pointed in the direction of Byron, who is sitting watching the giant chess games. She shows him Sean's photo and Byron recognises him. He tells her that Sean fainted when he arrived; his daughter, a GP, helped Sean and since then, Sean has been helping her out. They've been in the bush for two days, waiting to deliver a baby. Byron offers to drive Tina out to them and they set off. As they are driving across the scrub, in the middle of nowhere, Byron suddenly blacks out; the truck skids off the road and comes to a halt. Tina tries to revive Byron but fails, though he's still breathing. She tries to start the truck but the engine won't start. She sets off on a path, following a signpost to a village.

Josh and Penny are called out to Martin Cross by his neighbour Ruth. He has scalded himself but Ruth says that's not the real problem; Martin has Aids and also has pneumonia. He is taken to A&E where Patrick treats him. They ask Martin if they should contact his next-of-kin, his mother, but Martin doesn't want them to. He says that it only upsets his mother to see him like this, so they agreed that she wouldn't have to. Martin knows he's dying. Patrick is pushing Adam to find Martin a bed. Adam says this is because Martin is HIV positive and Patrick wants to get him out of the department as soon as possible as he's scared Martin will infect him by breathing on him. Ruth comes into A&E and Patrick talks to her; she tells Patrick that Martin wants his mother to remember him as he used to be, with some dignity. Patrick goes to see Martin. He's read Martin's notes and found out that he's been doing drug trials. Patrick suggests he join a drug trial scheme starting here next month. Martin says it won't stop him dying, but Patrick suggests it might give him more time to see his family, to see his mother. Martin says he doesn't want to see his mother.
