Something is up with the man in orange

Dsaf au I made ages ago)
Despite only working at Freddy Fazbenders for a short time, everyone began to notice how Jack changed. He was always beaten black and blue when he came around, always barring a new deep wound and without a smile. That's what angered Dave the most, the fact that someone had stolen his orange babies smile. Now, after Dave saw a scar that is present of Jacks back, he is determined to get to the bottom of what happened to him.
