Maddy is nearing her first change and feeling tired, tetchy and teething too, the wolf close to the surface. Her mum wants her to stay home, but it is exam week and Maddy has worked too hard not to go in. Her mum gives her a formula to help keep wolf symptoms at bay, but Tom accidentally smashes the potion within the first 5 minutes of arriving at school! Being dyslexic, Tom is nervous about the English exam but Maddy forgot to go over to his the night before. She promises to help him at break-time instead. However, Rhydian tells Maddy the best way to ease pre-transformation nerves is to go for a run. Completely forgetting about Tom, Maddy takes off with Rhydian. Realising what she has done, Maddy feels awful, but Jimi has come up with an alternative solution for Tom - cheat! If Tom takes photos of the paper, they will both breeze through. Shannon and Maddy fall out and Kara asks Shannon to study with her for the science exam. The stress of the maths exam makes Maddy start to wolf out. Rhydian sees this and to stop anyone discovering her, he hits the fire alarm. The class is evacuated. He gets in big trouble - but Maddy is grateful. Later, Maddy goes to see Shannon studying with Kara in the science lab. She apologises for being so snappy, but Shannon is having none of it. During the ensuing row, two chemicals are spilt and slowly merge together. They catch light and Shannon, trapped by the fire, is concussed. Maddy raises the alarm and tries to help, but wolfbloods have an instinctive fear of fire and this causes her to partially wolf out. Shannon, coming to, witnesses this and is terrified. Rhydian raises the alarm and Tom rescues the two girls, but Tom doesn't believe Shannon's story, and claims she was hallucinating. Tom decides not to cheat after all.
