Janet and Richard prosecute Ben's grandfather's murderer but for Janet, her worst adversary proves not to be the Defence, but her own body.Janet steps in to prosecute Cooper for the murder of Ben's grandfather. Ben has to convince Janet he will make a good witness. Ben is under pressure from his father, Geoffrey, who wants to see a conviction at all costs. Ben also discovers that Justice Rosenberg is listed as the trial judge which means Julie will be sitting on the trial too - a dangerous scenario, given they are sleeping together. As the trial gets under way, Janet is faced with one obstacle after another. But advice from Tony identifies Cooper's mate, Mozza, as the weak link and he eventually cracks under Janet's cross-examination. The verdict comes in: guilty. Janet and her partner Ash (who we learn is a woman) get the ultrasound of their unborn child. When Tracey finds the images in the DPP, she jumps to the wrong conclusion, treating it as evidence of Erin's affair with Rhys. Erin, still swamped with Stone/Mervich, sends an inappropriate SMS to Rhys by mistake. After a celebratory party at his newly reclaimed flat, the roof falls in, forcing Richard to move back in with Tatum.
