Lucy is selected to represent the school in a Science Competition, to build a working rocket. She feels confident she'll win, but when she starts work on the rocket it soon becomes clear that it isn't as easy as she thought it would be. Sophie offers to help - and Lucy is suddenly confronted by two equally horrible prospects: failure or cheating. Josh wants to go to Holland with the hockey team. But Josh too has a horrible choice to make - because sucking up to Lockett will mean he has to ignore his friendship with Frankie and Pete. Brian enters one of Mel's photos for a competition - a rather glamorous self-portrait. Mel is furious and goes to withdraw it, but when she discovers she might win she decides to leave it in the competition. Mel eventually comes second, which Brian and Sophie simply understand as losing. So in order to make up for her disappointment, Brian pastes copies of the photo of Mel all over the school with ""We're sorry sweatpea"" on them.
