Congratulations you unlocked the "oopsie" ending.
Call out to him
Wondering what he’s doing you call out to the man. Who turns around and greets you cheerfully. “Why hello there who might you be? He asks and you give your name as you walk up to him. Then as you approach, you realise that the man’s apron is covered in blood. and that there’s a half horse half man abomination lying on the floor. And that it’s breathing. You look at the beast, back at the man. You notice his eyes aren’t smiling. “How nice of you to stop by,” He says “I’m sure I can find a good use for you.”
