Don't worry, he was just as surprised at the train's ability to have duplicates, too. Parallel world Lan Wangji told him all about that madness almost as soon as he'd arrived because there had apparently been a different Sizhui at some point. For reassurance, the boy nods, though he doesn't say much else on the subject; it's an odd one to discuss and he'd prefer not straining himself by thinking too much.

Good thing it isn't only Sizhui's space, huh? There's one other person he's roomed with at the moment who is on the opposite side of the room, their belongings different from his own. The bottom bunk he's taken has his sword, qiankun pouch, and one of the reed butterflies from home alongside some other baubles and glass trinkets he's collected during his five months on the Voidtrain. Carefully made paper haitang flowers litter the wall in an array of colors too, a real small area that's similar to his old bedroom, despite missing some items here or there. (How unfortunate, he probably doesn't remember those stories, as he would've recalled them fondly...)

“Of course.” He gestures toward the lower bed, the upper one already neatly folded up and out of the way so they can sit at the makeshift bench with an attached table.
