Billy's nothing like usual. He was never a "normal" type of guy, but something's changed. You see it.

Today, Billy offered you a drive back home, and you agreed, not only because you didn't want to go back by foot but because you were curious. He was more silent than usual, distant, cold. Nothing like the devil-may-care guy you knew.

You get a weird feeling when he brings you to the abandoned still mill, The Brimborn Steel Works, instead of your house. What's happening?
