When John arrives at the exam marking course and introduces himself as Colin Fishwick, he panics when he spots ex-colleague Charlotte. Backed into a corner, he's forced to reveal his identity fraud in order to stop Charlotte from blowing his cover. Charlotte's intrigued as John explains everything and pleads with her to maintain his cover. But as Charlotte flirtatiously toys with him, will she play ball? Meanwhile, as Leanne and Peter continue to row, she insists that Nick should keep his distance and grateful that she stuck her neck on the line for him, he agrees. Back at home, Leanne states that nothing's going on with Nick but Peter won't let the situation lie. With that, Peter reveals that he's checking if Nick's operations from the Turners' property is legal. While Leanne accuses her fiancé of acting like Ken, Peter persists in his accusations - it's obvious why she's sticking up for Nick. A furious Leanne, however, can't believe that Peter doesn't trust her after all they've been through. Jason notes that Tina seems distracted - it's clear she's having doubts about being back with him. Worried that she's slipping back into the depths of depression again, Jason turns to Graeme for advice. Graeme comes up trumps but when Tina realises that Jason's romantic gesture was down to Graeme's insight, she's thrown into turmoil. Elsewhere, Ciaran's charm begins to wear Michelle down; Lloyd avoids Cheryl; and Owen tells Ches that he can still work on the market stall on the condition that he finishes his exams.
