 The school secretary, Mrs. Mason, brings her nephew to school, Bevis who wants to supply sweets to the tuck shop. Lucy and Jodie aren t impressed, until he shows them the chocolate hearts, and they negotiate a deal. They decide to promote a "Friendship Day" to sell them. Mick and Barry use strong arm tactics to try to persuade Gary to do their art course work, but they are disturbed by the arrival of a policewoman in the playground. Nick finally comes to clean with Natasha about stealing her diary: to his surprise, she doesn t go mad at him. But, later, she questions his motives, not really believing his reason for putting up the diary. Dennis buys a friendship heart, and hides it when Andy appears. Dudley has an adaption of the "apple for teacher" idea - he spills bird-seed into Mr. Parrot s register! His class is unruly when the teacher appears, continuing to make awful puns at his expense. In the corridor, Bevis, passing by, introduces himself to Ray as an old friend of Kenny s. He tells Ray they used to call him Sting, when he was little ("Sting-ray!"). In art class, Mick shows some severe homophobia when he reads about Michelangelo. A policewoman gives a lecture about personal safety to the Year 10 s. Jacko mentions that sometimes violence occurs without the parents knowing - this sounds warning bells in Mrs. Monroe, who questions him further. After they ve exchanged chocolate Friendship Day hearts, Dennis finally gets round to asking out Lucy. Andy is overhearing, and tells Dennis not to worry about Lucy stalking him. In the common room, Nick gives Natasha a friendship heart. Then, Richard is about to give a juggling demonstration, egged on by a cheery Nick, when suddenly Natasha explodes with fury. She tells them they are a bunch of liars and thieves, and exposes Nick as the one who copied her diary, and then tried to buy her silence with a 20p heart. She leaves, giving back the sweet to Nick on the way out. The others follow her, leaving Nick alone in his despair. As the day draws to a close, Lucy asks Mrs. Mason if they can get some more hearts off her nephew. Maria asks Mr. Brisley for help with her art, but he tells her that he has no time, and can she call him at home. Outside, Dennis tries to shake off persistent Andy, so he can meet up with Lucy. His delay makes him too late, and he finds Lucy has already gone. When Ray goes home, he finds Bevis making a re-acquaintance with Kenny. To Ray s disgust, it seems Kenny s decided that his old friend is to become his best man...
