Paintbrush, who you were somewhat friends with, had recently gotten into an argument with some of the other contestants which resulted in their bristles/hair turning to fire, ( which happens when they get mad or frustrated) and then storming off. You had been chosen to try to comfort them since everyone else was to nervous to do so.

You knock on the door, "Paintbrush? You okay in there? Everyone is really worried-" you get cut off

"I'm fine! Go away!" Paintbrush snapped from inside the room.
