Blissfully unaware of John's presence, Arthur puts a hand on the endcap and then pushes his cane out as far as it'll go in a couple of directions (it slides freely into open space), and then more carefully in a couple more (it taps against the bottoms of displays).

"Layout seems to be the same so far, thank god..."

So far. "Wonder if anyone's managed to map you yet," he says, thinking aloud, as he explores further into the store-- only to get jumpscared by a motion-sensitive spooky clown on display, because of course he does. It screeches and cackles as he walks past, and Arthur jumps out of his skin with a hissed "jesusfuckingchrist". For a moment he looks like a cat trying to decide if it should attack or flee.
