Wei Wuxian's efforts at present are temporary deterrents and redirections, a fact he's well aware of as he allows the last note of his song, coaxing as it'd been, to linger on the night air. Sound attracts these dead, he's noticed, but in his case, it also shifts them offcentre to their original purposes.

He smiles in return to Zewu-jun's expression, but the immediate greeting of didi startles him badly enough he goes wide eyed and starts coughing. Waving Chenqing between them, the staving off of asking if he's lost his mind spontaneously, or at least failed to perform basic functions of breathing, before he manages a smoother sounding, "Ge," like that isn't the single most perplexing thing to be referring to Lan Xichen with in the worlds.

Which, given Wei Wuxian hadn't known he was married in Lan Wangji's mind for decades, and time yet here, and had dragged it out of him, he concludes (erroneously, perhaps, but what seems correct from his perspective): "You've reunited with Lan Zhan already, ah?"
