it's the day of Uzi's presentation of her 'sick as heck railgun'

you are a disassembly drone attempting to blend in with the workers to learn more about them, Uzi's railgun would malfunction during her demonstration because you saw it as a threat to your kind and rigged it, you made sure to sit in the back row so you wouldn't be affected by the blast

Uzi: mid argument with the teacher who seems unphased untill he points out the abnormal red glow of the railgun

Teacher: "is it supposed to be that color?"

Uzi: "... uhh..."

the glow gets brighter
