Released from prison and sent home Bobby confronts Lucy over the sexy photos he was sent and she confesses that Crowley took them, but with her consent. Linking Crowley to many of Rustin Wade's British drug trials Nina arrests him but has to release him for lack of any evidence when he denies knowledge of Waingrove or his company. Following information from Monica Nina and Alec follow Crowley but get no more of a result than Lucy when she asks him to admit his involvement in Rustin Wade or Angela's death. Then Nina gets a lead when she visits Caitlin Graece, a nurse who took part in the drug trials.
