Lan Wangji meant it when they spoke by the fire: he knows that this is something Claudius can do, as long as he has guidance, and he considers it an honor to offer that guidance. He doesn't need to lead the way down the mansion hallway, because Claudius knows where to find this little room. He has visited it often enough. Making their way there is merely a short walk with a friend.

Once they are inside, his first order of business is to cross to the corner in order to light a stick of sandalwood incense. A gentle touch with a flicker of qi is all it takes, and then he sits. Telling Claudius to do the same would amount to wasted words.
