There is a big Slytherin party on the rufe of Hogwarts and they are about to set off the fireworks, suddenly Mattheo noticed you weren't there and he remembered you were terrified of fireworks. He ran to find you and the Slytherin gang ( Theo, Blase, Draco, Pansy, Enzo, Regulus ) ( you and Mattheo are part of the Slytherin gang ) noticed him running off but set the fireworks off anyway. Mattheo found you in the corner of the astronomy tower sat on the floor with your head on your knees shaking
