"I think in the long run that would be the least embarrassing option for everyone." 

Wen Qing comes over and makes a good try of prying Lan-guniang's arms away from her sister.

No.

This isn't working. "I can use my needles."

"Iiiiii'm not sure what happens if a drunk impulsive Lan Zhan wakes up to being stabbed but I'm not sure it's worth it." 

"Are you sure?"

"She could actually hurt you! She's disoriented enough she had no idea which direction the tent was in despite the fact that it was plainly visible from where she was!"

Sigh. "Alright. Sleep well, then. A-Ning and I will take care of watches."

"Thanks. Sorry."

"Goodnight, Er-jie!"

They split two shifts for keeping watch, but the night passes uneventfully. 

She wakes at dawn with her face tucked against something soft and warm.

Lan Zhan stiffens in shock. She backs away slowly, staring at -- skin, and then someone's neck, and then -- Wen Ying's sleeping face.

She releases her and scoots three feet away across the tent in a single instant, gasping. What happened??? How -- she doesn't remember. She doesn't remember last night at all, not after -- the fire, and Wei Ying's lips, and wine.

Wen Ying makes an unconscious little noise of protest and snuggles in closer. 

AAAAAAAAA

Oh god how did this happen what did she do? What does she do. Wen Ying's hair smells so nice she cannot survive it.

Okay. Okay. She will just - meditate, until Wen Ying awakes, as she often does in mornings. Whether Wen Ying is snuggling her and making endearing noises or not is Completely Immaterial.

She wakes a few minutes later, yawning. 

"--Hi. Sober now?"

She releases her lightning-quick. "I --

Last night, what did I...?"

"You got drunk in seconds on one cup of wine. Qing-jie is the best doctor ever and she was baffled. You were completely out of it, you couldn't sit up straight and when nine o'clock came and you decided it was time for bed you walked off in a random direction. I had to grab you and pull you to your tent and then you wouldn't let go of me." 

"I apologize. I have never..."

"Hey, when a doctor like Qing-jie has no idea how something is even possible, you don't have to feel guilty for not having anticipated it." 

"It's quite unprecedented," says Wen Qing from the center of their campsite. "I believe the Gusu Lan alcohol restriction may be a matter of self preservation, if this is how a single cup can affect you!"

"Well. Time to pack up the tents, no?"

Yes absolutely she will happily focus on tents and anything other than her Shame.

"--Seriously, it's alright," she murmurs after a little while. "I've done sillier things while drunk than walk in the wrong direction and hug people, and I drank a reasonable amount of alcohol to get there." 

It's fine. They don't need to discuss it.

Working all together, the campsite gets packed up quite quickly. They set off downriver again as the sun crests bright over the hills.

Hours later, they reach a sharp bend in the river. The Yin Iron still wants to travel onward straight ahead, southwest. Lan Zhan guides the boat to dock, and they can continue through grassy meadows on foot.
