What had happened, exactly? Test Tube had manipulated you all into joining one of her wretched experiments. All of you were going insane, you were the only one that is half sane. Paintbrush was banging on the glass, being a hothead, Fan was getting paranoid that his phone had run out of battery, Lightbulb was trying to lighten the mood (that got nowhere) and Marshmallow was trying to keep her sanity like you.
