You're Charlie/New Puppet, and your dimension is crumbling. There is a virus going around, The ruin virus. You didn't have the ability to cure people of this virus but you could send the virus back to stage one. But then everyone crashed down.

Eclipse is corrupted, he's barely even consciousness, Ballora is corrupted, she is raging at everyone, Roxanne is corrupted, she locked herself in a bathroom saying she didn't want to hurt anyone (you had to forcefully get her out), and Sun was corrupted, he was lashing out at FC, who'd tied him up. Monty was working on a device that could fix everything, and Ruin... Ruin was still deadset of saving his Monty. Literally, he was loosing it. You went back to parts and service after dealing with all the corrupted animatronics, you were exhausted. You stood beside Ruin, begging him, pleading for him to let his Monty go so he could help save the whole dimension. The whole world at that. Finally Ruin snaps. He turns to you, and slaps you across the face so hard you fall to the ground

Ruin: "I DON'T CARE ABOUT THIS CURSED DAMN WORLD, I JUST NEED A FEW MORE DAYS!!! DAMNIT CHARLIE!!!"
