Thinking about the parallels set up between Wei Wuxian and Mo Xuanyu, and how actually most of them are oddly specious.
The sketch of the backstory lines up, but on close examination they're mirror images.
Wei Wuxian wasn't kicked out of his sect, he left it. Wei Wuxian didn't hate the house he grew up in, he loved it, and getting the people there killed was the absolute last purpose for which his dark powers were ever intended.
Jiang Cheng was no Mo Ziyuan--his jealousy was a complicated thing all twisted up with love, and while he would lash out at Wei Wuxian both as a casual means of shit communication and more damagingly in moments of high tension, he had neither the desire nor the ability to bully him, and in general respected his boundaries almost too well.
When Wei Wuxian destroyed himself about Jiang Cheng, it was to give him cultivation, and protect his life and happiness. He would never have killed him.
Madam Yu was a domineering aunt-like figure, who hated Wei Wuxian for reasons of reputation, and because she had resented his dead mother, but she crucially did not have the power to actually disrupt his lifestyle to any significant extent.
Mo Xuanyu was shut up in a small room to rot; Wei Wuxian didn't even attend classes unless he wanted to. Mo Xuanyu was weak and disliked; Wei Wuxian was brilliant and popular.
Mo Xuanyu's uncle is a cipher of a figure, without character or agency, a nonentity who is resented to death apparently mostly for what he didn't do; in theory he is the master of the house, but he certainly never protected his wife and son's punching bag from them.
And this is what got me thinking along this track: because people keep interpreting Jiang Fengmian as this, as exactly like Mo Xuanyu's nameless uncle, a nonentity who lets his wife make all the decisions, and is contemptible therefore.
He shows up in fic characterized this way all the time, handled narratively as a gap rather than a person, an absence where there should have been a parent, and it's...totally inaccurate? The man only has a few scenes but the things that are most firmly established about him are:
he regularly goes out of his way to protect Wei Wuxian
he's extremely fond of Wei Wuxian
he cares a lot about ethical behavior
he's conflict-avoidant and gentle
he can and will overrule Yu Ziyuan when he's made up his mind, and there's nothing she can do about it
his communication skills are mediocre at best
he doesn't understand jiang cheng
he has a dumb sense of humor
Now almost none of this made it into cql besides point 4 and maybe 6, 5 is technically there but buried by the cinematic framing, so I totally get why the fandom on the whole struggles to characterize him well, and it's easier to write him off.
But it keeps bugging me to see him and Yu Ziyuan squashed into the mold of the Mo, because not only is that boring and reductive and kind-of-missing-the-point, it's like. Wei Wuxian and Jiang Cheng's characterization suffers a lot when you alter the environment and take away the influence exerted by their shared father figure.
Jiang Fengmian was Wei Wuxian's primary adult role model and it shows.
Jiang Cheng's relationship to his own sense of ethics is fraught because 'teaching him good ethics' was his dad's number one parenting goal, but they misunderstood each other so badly (partly because Yu Ziyuan kept loudly misinterpreting them to each other, which is so realistic I can't get over it, that's exactly how it works good lord) that Jiang Cheng has a direct association between the concept of 'doing the right thing even when it's hard' and a feeling of personal inadequacy.
The fact that Wei Wuxian got their dad-person's approval for being exactly himself and Jiang Cheng not only couldn't do that, he couldn't even get that same level of approval when he really pushed himself to rise to expectations, because Jiang Fengmian did not intend that warmth as a 'reward,' and so never realized he was withholding it, and therefore misunderstood Jiang Cheng's visible jealousy as a dangerous sense of personal entitlement that had to be carefully restrained, which reinforced his distrust of Jiang-Cheng-the-person and fed into a shitty loop where they were less and less able to relate to one another--that's fantastic. That's so human! I love it so much.
Both their failures are their own but at the same time it would never have gotten so bad if Yu Ziyuan hadn't been interjecting herself in there, in the middle of their relationship, fucking it up. That's family, baby.
I would ofc like if there was more fic engaging with the subtleties of all this because it's so good, mxtx did such elegant work here and it is not sufficiently appreciated. But it's the kind of thing that's hard to write good fic about; I am struggling with it myself.
So mostly I wish there was just more fic that didn't impose Mo Xuanyu's cliche angst backstory on Wei Wuxian, who has a whole different thing going on.
