With HSC exams just a few short days away, Bolton rallies his classmates to make their Muck-Up Day an event to remember. Events however go horribly wrong when a fire breaks out in the school computer lab and Dyson eyes Matt as her prime suspect â€” and threatens to withdraw the entire class's HSC eligibility unless the culprit comes forward. Fortunately, while reviewing the video Charlie made of the days events, Katerina spots the real perpetrator (he's an old friend of Matt's who was kicked out of school and returned to settle the score) and Matt is exonerated. Charlie proposes to Katerina, but after her acceptance, they both begin to have second thoughts about the commitment and decide to put off their nuptials â€” much to Roberto's delight. The gang decide to create a time capsule to mark the year's end, and after burying it, Danielle announces to her friends that she's decided to take a reporter's job offered to her by a television station in Wollongong.

Matt's comfortable existence at Hartley High is threatened when his past comes back to haunt him. Paul - Matt's competitive, over-achieving father - wants his son to return home to his family and a more settled existence. Paul is convinced that Deloraine has let Matthew run wild - a belief that is confirmed when he sees Matt's less than impressive school results. Paul's worst fears about his son become reality when - angered by his father's domineering approach - Matt uncharacteristically lashes out on the basketball court, punching teacher, Andrew.   It looks like Steve is also in trouble. Everyone needs him: Con needs photographs for the school magazine, Allie needs help with finding a new flatmate, and Danielle wants to go to the movies with him. But Steve is missing.

They're not the only ones having difficulty coming to terms with Steve's death. Con just can't face putting together the school paper which is to be a tribute to Steve.
