Synopsis
Matt is showing the ropes to his replacement, David Sinclair, but Jude turns down an offer to go to Crete with him. A boy, Edward, is brought in by his father Craig and uncle Tim, but refuses to talk to Richard and Sam, leading them to suspect abuse. When his mother Paula turns up, she learns he fell down the stairs after finding Craig and Tim were having an affair and manages to reassure Richard. The warring families Lowthers and Muldowney descend on the department: Lowther grandmother Maggie was attacked and beaten in her home and her grandsons beat up Muldowney boy Conway in revenge. In fact, he is innocent; he has been seeing their sister Zoe, who is pregnant with his child. A fight in reception sees younger Lowther boy Lee knocked off a balcony and exposed as the culprit: Maggie disturbed him stealing money to pay his gambling debts. The older boys are arrested and a plea from grandfather Bill and the revelation of the pregnancy sees the mothers make a tentative truce.
