This is probably the only time Wrench will ever see Arthur without a cane; with more people in his house he's more awkward, ghosting closer to the walls with his left hand outstretched, enough to find it so he doesn't have to bump into anyone, but there's a level of confidence born obviously from familiarity that he doesn't seem particularly worried.

He does take a moment to step into the kitchen, though, obliviously passing Wrench by on his way to the kettle.
