Even though he'd seen the inevitable - human bodies cannot lose blood like this without a golden core and survive - Wei Wuxian whimpers as he feels Klaus' spirit detach from his body, the last clinging tendrils of it giving up purchase and lifting into the hair. Steeling his jaw, Wei Wuxian switches tack, grabbing at each of them and holding them to this plane.

He can't save Klaus, but he can hold enough of him here for Obi-Wan laoshi to say goodbye, for his poor Lan Zhan to guide him to rest with Wangji. Oh, it will be agony for them, and there's nothing Wei Wuxian can do. Chin trembling, he lets Klaus slump to the pavement, neck twisting for anything he can use. If only he'd brought one of Lan Wangji's Qiankun bags into town today, he could safely host Klaus' spirit inside, but - ah, there on the ground. A little plastic figure rests; a child's toy, surely, but it will do.

Wei Wuxian pulls Chenqing from his belt and begins to play, mournful notes first guiding and then tugging the tendrils of Klaus' spirit into the toy.
