The Untamed + I want a baby meme

In which Lan Xichen, nearly thirteen, visits Nie Mingjue, newly appointed Sect Leader - and decide to swap brothers for a day.

The healers said it was trauma. Perhaps he was too young, or too sensitive; perhaps it was only that it had happened in such a way, at such an impressionable time – in any event, Lan Wangji’s reactions to his mother’s death had gone well beyond the normal signs of grief and turned into something much more severe. After some intense discussion, it was agreed that he should be temporarily sent to live as a guest in another sect to see if he would benefit from the change of scenery. From not being around the place where he was drowning in the memories of his mother. They sent him to the Jiang Sect.

HOLY FUCK IS THAT A BABY?! The howling anguish of the Burial Mounds goes silent. Wei Wuxian has returned, and he has brought other people with him, and one of those people is, indeed, a baby. The little caravan of weary living people (who have a fucking baby with them) works its way up what might generously be called a path, deeper into the cursed hills, and they have the full attention of many, many ghosts. Resentful energy burns away, boiling into nothing under the utter shock of the situation. Who the fuck brings a baby to the Burial Mounds? Or: People think Wei Wuxian somehow cleansed the resentment of the Burial Mounds for the Wen survivors, but actually, the ghosts did it as babyproofing.

Crumpled at the base of Koi Tower’s long stairs for the second time, Jin Guangyao presses his face into the stone, takes a deep breath despite re-broken ribs, and arranges his features as carefully as he knows how. Then he stands, moving carefully around the pain, and bows deep, arms held straight and true. The walk back up the steps to his father's side is painful enough to wipe the smile from his face; it is not painful enough to prevent him re-taking his place as seneschal, bowing again at the top of the steps. As he straightens, he prioritizes his plans for his father’s demise over all else.

Well, shit, Nie Huaisang thought, even as he comforted Jin Rusong, petting the toddler’s back to try to get him to calm down. What do I do now?

“Hey,” Lao Nie protested mildly. “Who’s the father here, me or you?” “If a-die wants a new wife, little uncle will find one that isn’t inclined to kill him.” That sounded like a recitation. “Then what’s even the point,” Lao Nie grumbled, and reached out to ruffle his son’s hair, enjoying how Nie Mingjue yelped when he did, glaring up at him with offended dignity.

Nie Huaisang’s rooms in the Unclean Realm had a little side door that no one but him ever used. Years after he’d put it out of his mind entirely, there came a terrible banging noise at that little side door, like someone was kicking at it furiously from the outside. Lan Wangji, white robes stained with blood and cheeks bright with fever, shoved something into his arms. “You have a child now,” he said through bitten lips. “Congratulations. He is called A-Yuan. I entrust you with his care, for my sect cannot be trusted with it.”

Prompt: Nie Huaisang buys Jiang Cheng a “baby on sword” (like baby on board lmao) pendant as a joke but Jiang Cheng actually uses it
