(be one of them) Fan, Paintbrush, ~Marshmallow~ and Lightbulb were trapped in room 21 of Test Tube's lab. They have been trapped here for weeks. Everyone is mentally or physically scarred. Marshmallow dying, Lightbulb shattering (she still has the scar), all of it. Test Tube just said she was going to hurt Fan severely because he tried to escape, With Lightbulb watching.

Test Tube: "Well, there are many ways I would hurt you. Which one would hurt Lightbulb the most?"

Fan: "H-How about none?"

Paintbrush: "You can't do this! It's psychotic!"

Lightbulb runs in front of Fan.

Lightbulb: "Please! Hurt me instead! just don't hurt him!"

Test Tube stuck Fan's arms to the walls using duct tape.

Test Tube held the edge of Fan's paper. Just above his right eye.

Fan: "You wouldn't."

Test Tube: "Oh, 3. But i would."

Test Tube then proceeds to rip Fan's paper down to his right eye. She had completely ripped across his right eye. That's where she stopped. She didn't rip any part off, just made a tear.
