"Uh, they did that because I am a wizard and they do not want me to be." He's just going to start walking, in the hope that this will not be a torture cabin. 

"Magic is real?" Lan Wangji says in a flat tone of voice that gives absolutely no information about how surprised he is about this fact.

"I can demonstrate, but the easiest proof is, uh, kind of gross?"

"You wouldn't lie."

"I'd like to think that if I was lying, I'd come up with a better one?"

Walk walk walk walk walk walk. 

He is walking! While very confused about Lan Wangji's angle. "-- how did you even know I was kidnapped?"

"My sister is dating Meng Yao."

"Oh. Oh no. I am so sorry?"

That doesn't seem like a sentence that needs to be answered.

"I'm surprised she told anyone."

"My sister mentioned you were sick. Meng Yao looked shifty. So I hacked into her computer."

...all is revealed. "You can hack?" Lan Wangji was a software engineer, sure, but he seemed too straight-laced to even consider putting on a black hat? Especially because someone he doesn't know knows Wen Ning looked shifty? "--We should probably make sure my sister knows I'm alive." For now.

"I can send her an email. Through several proxies."

"That would be good. -- How long was I gone?" How many people think he's dead? Have we changed presidents? Have South Korea and Australia gone to war over Cosmo's editorial policy?

"Ten days. I'm sorry."

"I mean, I was worried it might have been a month?'

"Mn."

"So hopefully no one's filed a death certificate for me."

He is so good at walking long distances. He has Wizard's Body and everything. He is definitely not stumbling!

Lan Wangji picks him up again. 

"Sorry-- I mean, you don't have to do that?" 

"Mn."

He is now being carried into the woods after being-- unkidnapped? Kidnapped twice? Also apparently he hasn't eaten for ten days and he's pretty sure something has gone screwy with his sleep cycle.

Lan Wangji is very warm and solid, and it is surprisingly hard for him to keep his eyes open. 

Some time later he will be half-woken-up by being placed in a bed. Maybe someone is kissing his forehead, but probably that's just a dream.

He says a half awake "thank you."

... the bed isn't as warm or snuggly as Lan Wangji.
