Genuinely one of my least favourite fanon things that people often believe (or just say) about MDZS is the idea that Lan Wangji was waiting for Wei Wuxian in those thirteen years. Like, I know it's fun for jokes and all but one of the most crushing parts about all of that time is that Wei Wuxian literally was dead for thirteen years and there was literally no conceivable hope of him returning.
Like, by no means am I trying to weigh up the MXTX love interests' separation periods (as I like to think of them), but Hua Cheng had hope that he would find Xie Lian - he had so much hope that he actively searched for eight hundred years for him before he found him. Luo Binghe was able to bring Shen Qingqiu back, was in the midst of doing so when the mushroom body situation happen and then (while it wasn't Luo Binghe who did it) did bring him back.
Wei Wuxian died. Like straight up, no coming back, impossible to see him again, died. And I sometimes feel like saying that Lan Wangji was waiting kind of undermines the fact that this was a soul-crushing thing, and this was just going to be the rest of his life. There literally was no fucking shot of Wei Wuxian coming back in anyone's even remote comprehension, and the fact that he did come back was a fucking miracle in and of itself.
Lan Wangji mourned for those thirteen years. Hua Cheng searched, Luo Binghe (it's been a while so call me out if I'm wrong) was almost in denial over Shen Qingqiu's death even though he comprehended the sacrifice so he planned, but Lan Wangji mourned, and was going to mourn for the rest of his life. He just had to get used to the fact that he would never, ever get to see the love of his life again. There wasn't even a body to bury. It was just the memories and the gradual, slow descent of those memories disappearing with aging.
ALSO now that I'm thinking about it, the fact that he couldn't even talk to anyone else about it. Obviously, there's this whole thing of memories being kept alive through like sharing and talking about them, but Wei Wuxian cemented himself as basically a taboo subject. A monster who is only talked about to scare people or to curse out his name. Those who remember him can't or won't talk about him for one reason or another, and that means that Lan Wangji is left all alone, mourning someone who nobody even cares to talk about, and that will be the rest of his life. He has come to terms with the fact that he will die with the faint memory of Wei Wuxian's smile and that's all.
And, once again, this isn't trying to make a competition out of the separation periods, I could just as easily talk about how Hua Cheng's despair of not being able to find Xie Lian but knowing that he is alive somewhere (or is he? Has he gone? Faded away? Is Hua Cheng just looking for a memory?). I could talk about that desperation that Luo Binghe felt at losing the only person he had ever loved and been loved by, who had sacrificed himself to save him when he needed him most, who gave so many mixed signals, and then needing to get him back by any means necessary. But this post was borne of me being tired of the 'waiting' label being applied to Lan Wangji's mourning period.
Wei Wuxian was never, ever meant to come back. Lan Wangji was going to spend the rest of his life mourning a man who nobody else would ever talk about, memories fading until it was hard to pick apart what was actual memory and what was just his idealistic daydreams. Do you think he was waiting to die, sometimes? He never would, but do you think he just...passively waited for it sometimes, when he was alone and holding those few small reminders of the man he gave his heart to? Who he failed? Anyway. Lan Wangji just makes me so very sad and so very sick and I love him dearly.
