Sure seemed like the part he was sulking about. "Then what are you asking?"

"Why didn't you tell me afterwards?"  

"It wouldn't be fair to you if you knew."

"Fair to me...?" he echoes, puzzled. 

"What.  Because you can't trust me not to start shouting it to the whole world and embarrass myself?  Wei Wuxian telling me to be more careful of my image in front of others?  Well.  Given what I immediately ran off and did after Wen Ning told me, that's probably accurate."  

"Are you serious? No! Because it's - made you all upset, just like this! When you didn't ask for it and you wouldn't have accepted it, how is it fair to dump a thing like this onto your lap? It would be unfair for you to know and feel bad."

"So instead I spent the entire time up until you died harping on you for not using regular cultivation.  How much demonic cultivation did you do, just so that it wouldn't look suspicious?"

"I don't know, Jiang Cheng, so far it hasn't been any. I don't know how much it was in the future you came from. I can't tell you."

He nods. 

Jiang Cheng starts wiping the blood off of his hand.  Suibian still needs to be cleaned, and that at least is a manageable amount of mess to deal with.  

"I can go get some water for that."

"That's a good idea."

He ventures downstairs to retrieve some more water from the innkeeper.

And he wakes, first to an empty bed and then to the sight of — an empty room, no sign of Wei Ying, and Jiang Wanyin is cleaning blood from his hands —

Wangji bolts out of bed, Bichen flying to his grip, eyes wide with fear. “You —”

Jiang Cheng jumps up at the metallic noise of Bichen's movement.  His hand moves towards his own sword, ready for danger.  Lan Wangji is looking at him?

"Lan Wangji.  Do you summon Bichen and threaten the first person you see every morning?"

"Where is Wei Ying?"

Jiang Cheng glares.  He doesn't appreciate how Lan Wangji keeps pointing a sword at him.  And now Sandu has blood on it's hilt where he grabbed it.  That's one more thing that needs to be cleaned.

"He'll be back soon."

"What did you do?"

... Actually saying 'I grabbed the wrong end of a sword and sliced my hand open,' is far too embarrassing for Jiang Cheng to manage.  Also none of Lan Wangji's business.

Wangji runs past him, Bichen still drawn, and darts out into the hallway of the inn. He doesn’t know where to go, what he’s expecting to see, but Wei Ying isn’t in the room and that means Wangji needs to find him —

Wei Ying is halfway up the stairs from the inn's lobby, carrying two jugs of water on a small wooden tray. He blinks. "-- Lan Zhan? What happened, are the Wens --"

Wangji lunges forward and grabs his arm. "Wei Ying."

Wei Wuxian flinches, jerking his arm back.

A dull pain bursts low in Wangji's stomach. Even after their discussion last night, his touch is unwanted. That's -- fine. Whatever Wei Ying needs. He lets go of his arm. "Where are you hurt?"

"What?"

"Where did Jiang Wanyin hurt you?"

"Did he tell you that I got hurt?? Lan Zhan, I'm fine! Look at me and how well I'm carrying this water tray, I'm good as new. Aiyah, what's gotten into you?"
