If Forte had possessed a sense of smell when he was a robot, he probably would have recognized this large hallway immediately. As it was, he was just reminded slightly of the hardware store - it definitely smelled like freshly oiled metal. But as he turned off his flashlight and looked around, he froze with recognition. Although there were no overhead lights, there were bright lines tracing patterns along the walls, and in the distance, there was the sound of machinery and construction.
The guard robots and booby-traps hadn't been activated, but he would know Wily's designs anywhere. He was in Skull Castle. In fact, upon inspection, it was the same version he'd been taken from. He was... home?
"I... what... I don't... what?!"
After gaping a moment longer, he looked down and started inspecting himself. No, he was still human, still wearing that stupid uniform. What did this even mean?
