[ He's not offended by the second glance Rodion gives the potato. One should do their own due diligence and double check what they're putting in their mouth. It's good practice. ]

The properties of our rooms remain unclear to me. Miss Faust has not given me a thorough explanation. Nor did I assist her in designing these rooms when we built Mephistopheles, so I am not familiar with those details.

[ Yi Sang pauses for a moment, realizing he's getting carried away in his explanation. Rodion probably doesn't need to know that information, nor is she likely to be interested in it. So he shakes his head, as if to clear his mind of those thoughts. ]

Then again, as one has noted in the past... if an item resembles a potato and tastes like a potato, then, surely, it must be a potato. Perhaps that is all which ultimately matters.

[ Either way, he's pleased that he can offer Rodion something in return for the ginger candies, even if neither his expression nor demeanor shifts one bit. The corner of his mouth does turn downward in a pensive expression at her question, and he glances around the room while considering her inquiry.

He doesn't actually mind the questions. There's nothing to hide, especially not after the Sinners had taken a walk through his memories. ]

...there are some differences, yes. In particular --

[ He points at the twelve frames on one of the walls. ]

-- that wall was bare, just like my work bench used to be. The potato you hold and the vase holding a spicebush branch, neither of those existed within these walls.

[ There's another pause as he screws the jar of ginger candies shut, turning it in his hands. ]

...I suppose the room was quite sparse. There was no need for possessions while I considered my life futile.
