YOU ARE LIGHTBULB!

Things were getting heated during the card tower experiment Test Tube had made for you, Fan, and Paintbrush. She wanted Paintbrush to join her in experimenting, to which he said no.

Suddenly, Test tube had her leg up against Paintbrush's hip. She tugged violently on their arm, and they yelled in pain. They struggled and fought with her, but her pulling became more forceful.

Then the room echoed with a snap.

Paintbrush’s upper torso was held up in the air by Test Tube, as she stepped back in horror, dropping Paintbrush to the ground. They coughed up blood and looked god awful…

You ran over to their side, tears streaming down your face as you grabbed their weak hand. Then, the realization came to you. They were fighting for you. Paintbrush kept fighting to survive, though there was no hope to save him.

You knew you had to try talking him out of it, to end his suffering and let him rest. But you didn’t know how, and when you tried to speak, tears would just take over you.

(You)Lightbulb💡:“Painty.. please...”

Paintbrush🖌️: “...I... I... I... w-won't…”
