"Surely there are no worlds so small." He isn't dismissing the possibility but that didn't seem like it would qualify as a world. Worldlet. Not even a worldlet, just a platform.

There's a what-if scenario he could introduce at dinner to give everyone headaches. Rationalize an entire world the size of a platform such as this.

He sighs, when he himself is brought into the equation. "If you recognized where I was from, I would find that more surprising than unfamiliarity. It's an irritatingly ongoing mystery." One that would one day be unraveled, he's sure of it! "One of many."

Well, that's neither here nor there, nor important at the moment. "From an exterior perspective there would be no way of knowing. The subject would merely ... find themselves somewhere else." He frowns, tapping his chin. "While it would NOT explain the change of clothing, I have heard through certain knowledgeable sources that such magics exist as to shroud visitors in the appearance expected of local people and thus avoid a fright."
