Dark Matter shakes his head at the filly's antics before beginning to wander around, inspecting the place. Whoever did it, they were certainly thorough. Who might, though? And why? I guess it's possible somepony did this as a prank, but what would be the purpose?
He pauses his musings as he trips over a throw rug somewhere in one of the front rooms. He stands up and dusts himself off, though he probably doesn't need to, all things considered, before looking at his obstacle. Whoever did this really knew what they were doing. Everything is coordinated, if a bit over the top. I haven't seen anything this fancy since moving from Canterlot. Except maybe that dress shop.
On a whim, he decides to call out. "Hello? Is anypony here?"
