His amused grin remains, and he has to make a concerted effort not to imagine Lan Wangji milling about Cloud Recesses, an entire tree under each arm. Lan Zhan seems... less amused, even studying him in a way that makes him doubt his answer. He's not sure what the Wei Wuxian from his mirrored world is like, but apparently their looks are similar enough to recognize him right away.

"Lan Zhan," he blinked, the story of what happened to his other self just seemed to grow more and more unbelievable, "you lied to them about who I was?"

That was perhaps one of the most difficult things for him to wrap his mind around. But either he was lying now (doubtful) or he'd lied then. Perhaps it was more a lie of omission? Hopefully his disguise had been enough to keep Lan Wangji from getting into too much trouble.

He had to choke back another laugh though, swallowing before he dared to ask, "you brought Lil'Apple to Cloud Recesses too?"
