Coronation Street has an Abi Webster-shaped plot hole going on right now. During Monday's hour-long episode of the ITV soap, the former drug addict spied her old dealer Dean Turnbull skulking away from the Webster's Autocentre entrance. In reality, he'd come to scare newcomer Cassie Plummer into squaring a £70 debt with him, yet Abi assumed that he was back on the scene looking to do some business with her.
