I still think it’s funny as hell that while LWJ was like “I just want to find either his body or his spirit so I can put him to rest and maybe talk to him one last time,” Jiang Cheng was like “I KNOW that motherfucker is alive I KNOW it I KNOW he’s out there doing his Wei Wuxian BULLSHIT. Like hell he’s dead!!! This is Wei Wuxian we’re talking about!!”
i have this headcanon that, when they were looking for wei wuxian during the war (the only time they could ever stand each others’ company!!!), it was actually the reverse. like, they were both stubbornly insisting that They Will Find Him, but deep down Jiang Cheng is kinda sure what they find is going to be his remains - which he is still determined to find because dammit he is not leaving his brother to rot out there!! but like, he’s already halfway to thinking of yanli as “my only surviving family,” he’s halfway to referring to wwx in the past tense, and lwj keeps glaring at him whenever he says “wei wuxian was -” because nope he does not accept this. lan wangji is not used to not getting what he puts his mind to! lan wangji, at this point, had his own brother go missing-presumed-dead and then show up again to lead an army and be okay! lan wangji is going to find wei wuxian and he is going to be alive when he does and that’s all there is to it!
and frankly, lan wangji’s willingness to believe that wei wuxian is Gone with a capital-G after his fall hits jiang cheng as a kind of betrayal. as the only other person who knows wwx was not stabbed, that he was still alive when he fell, jiang cheng feels that lan wangji should be on board the “he’s definitely not dead” train - but of course he can’t get up in lwj’s face and demand to know why he’s not, because they are very much Not Talking about who did or did not stab which other people that day.
Oh my god yes I love all of this so much.
With the legendary hug Jiang Cheng gives Wei Wuxian when they find him again after Wen Chao dumps him in the Burial Mounds, I do 100% believe that Jiang Cheng had already decided that Wei Wuxian was probably dead. He grabbed onto that shige like he had thought it was something he was never going to be able to do again.
I wonder now, too, how much their respective thoughts were about how Wei Wuxian felt about each of them when he fell from the cliff also colored their perceptions of whether he survived. I think that maybe it’s the case that Lan Wangji felt that clearly if Wei Wuxian was still alive and needed help, then the first person he’d come to was Lan Wangji—whereas Jiang Cheng’s suspicions that “if Wei Wuxian is still alive, of course he would want to avoid me as hard as he possibly can” turned out to be true.
Therefore, Lan Wangji knows that Wei Wuxian is dead because if Wei Wuxian was alive then he would seek him out (not 100% true, as we saw ourselves, but I will concede that Wei Wuxian finds it difficult to stay away from Lan Wangji for very long), whereas the fact that Jiang Cheng hasn’t seen WWX yet doesn’t mean he has to accept that he’s dead—a living WWX wouldn’t reach out to Jiang Cheng any more than a dead one would.
