It's coming up for the school fancy dress disco and Gabriel is going as SuperTeen, kitted out with a tight lycra outfit. There's just one problem: Gabriel has started getting erections, usually when he least expects, and with the costume being so tight, he needs to find a way to stop them. He's not the only one who has concerns about their outfit - Lara isn't confident with what she's wearing, and is persuaded by Monica to wear a costume from the school's last play instead. What they haven't realised, however, is that the last play was Mother Goose and now her goose outfit makes Lara feel sillier than ever. At the school disco, Gabriel and Lara feel awkward and overwhelmed, and want to go home, but Tony comes up with an idea that boosts Lara's confidence and saves Gabriel from his embarrassing situation.
