Robbie is shaken by a break-in at his flat. As he attempts to contact Will (on a work trip in Manchester) without luck, Deek arrives, concerned about his pal. Robbie admits his reliance on Will in times like these - he doesn't really know what to do. As Deek steps in to help, Robbie is starting to get paranoid. In the clear up, Robbie finds Will's mobile in the flat, left behind. He's shocked to see a number of missed calls from a mystery man - Edward. Immediately suspicious and despite Deek's attempts to distract him, Robbie gets more upset as his suspicions start to build. Worried, he even calls DCI Donald about Will's whereabouts. Robbie then comes across a locked drawer - Will's locked drawer.
