Matt has organised a special orchestra project and is irked when Michael insists that Tariq is included. Michael himself is trying to keep his distance from Linda and is troubled when Sian accepts Linda's help to input the grades. His instinct proves correct when Linda confesses to Sian about their tryst, but Sian's reaction to the news provokes unexpected consequences that could have serious implications for her marriage. Michael's world is rocked even further by the sudden arrival of Wayne. Meanwhile, Scout is over the moon when Mia, a mid-twenties MS sufferer, offers her the position as a live-in carer, but Em's recklessness threatens to jeopardise everything.
