The truth surrounding Bex's disappearance is finally revealed when a fellow pupil discovers a shocking secret. It sends shockwaves throughout Waterloo Road and tests Tom's recovery when he's forced to deal with the aftermath. Elsewhere, Sam and Finn's mutual antagonism develops in an unexpected way, and Jonah gives Cesca a dramatic ultimatum. Bex finally confronts Karen with the truth surrounding her disappearance when Wayne Bodley, a Year 11 pupil, stumbles across a compromising video of her and spreads the footage around the school. It couldn't be a worse time for Bex, as she prepares her speech on the day of the head pupil elections, and it's left to a still-fragile Tom to get to the bottom of Wayne's behaviour.
