Buffy - 1x11 - Out of Mind, Out of Sight
Marcie (the invisible girl) paints “LOOK” on four lockers - one letter per locker. It isn’t a much damage, but they will need to be repainted, so it counts. Marcie breaks a valve in the gas room in the basement. Buffy punches a hole in a door so she can unlock it. Marcie knocks Buffy through the floor of her ceiling fort area - Buffy falls through the ceiling, breaking some unknown glass object that was in the ceiling, and lands on a table. The table is destroyed.
Marcie spells out “LEARN” on a stage curtain with what looks to be five pounds of glitter. Similar to the painted lockers. It’s not really destroyed, but it certainly needs to be replaced.
