Max sees a young lad, Ben, hanging round the cubicles. Ben tells Max he's looking for his mate, and Max leaves him. As a cubicle is emptied, Ben goes in, and empties the bin onto a trolley, looking for needles. Max hears the noise and looks in. He realises what Ben is doing, saying it doesn't take a doctor to realise, just a parent. He tells Ben that Frank was a junkie but got help. Ben asks him for methadone, but Max says they don't have any. He gives him a bag of needles, though, telling him that at least he won't get infected if he uses them. Ben leaves, and goes round to Johnny's place, asking for some gear. Johnny refuses, reminding Ben that it was his New Year's resolution to give it up. He tries to persuade Ben to go back to his mum, but Ben says his stepdad will only beat him up again. Johnny goes out, and Ben injects some stuff. When Johnny returns he finds Ben in a coma, and calls an ambulance. Johnny is taken to A&E, and Max, with the team, saves his life. Johnny calls Ben's mother Amanda.

Amanda says his friends push drugs on him, and says she saw the needles - she thinks Johnny gave them to him. Ben tells her that Max gave them to him. As Max and Charlie are about to go and join the New Year celebrations, she comes up to them, and asks Max for a word. She accuses him of giving Ben the needles. Charlie says this isn't the time or the place, but Max says he knew what he was doing, and gave Ben the clean needles so he wouldn't infect himself. Amanda says Ben could have killed himself with the needles, and almost dies. She says she's going to make sure everyone knows what he did to her son.
