Continuity mistake: Monday 5th June 2006: When Becca first goes back to school, after her husband found out she was having an affair with Justin, she walks into her classroom and closes the door. The shot changes to Justin and then back to Becca and she is closing the door again.
Plot hole: Everyone is puzzling over who pushed Clare Cunningham off The Loft steps. However, when she comes out of The Loft onto the steps just before she is pushed, a CCTV camera is visible above the door covering where she was pushed, meaning that whoever did it should have been recorded. Even if this camera is not real, Warren stated that he would be able to "have you're (Katy and Louise's) every move on CCTV", meaning that somewhere in The Loft Justin would have been captured on camera.
