OMG, I had written all my favs some place just becuz, and now I have a place to let it all out!!!
Here goes: (Might be too long)
Wei Ying!!!! Lan Zhan shouting when he falls (Nightless City)
Wei Ying pestering Lan Zhan by trying to help all the time in the flashback
In the present - Lan Zhan never once wavered in helping Wei Ying
Jiang Cheng - The flashback as kids - where he cries after chasing Wei Wuxian away - When they both hurt each other somewhat outside the Burial Mounds because it had to be done and bringing Yanli to meet in her wedding dress and telling her to ask Wei Wuxian for a name for her kid - And that last last scene - when he remembers how close Wei Wuxian had been to getting caught and how that's how he must have gotten himself caught instead... omggg
Yanli - with lotus root and ribs soup which seemed to be the family solution for all their family problems - How she picks out the seeds when they are eating with their parents - When she defends him against the Jin clan clown at the hunt - When she is about to die she says he ran too fast for her to get a good look at him ... omggg
Madam Yu - When she stops beating Wei Ying and starts beating up the Wen irritating lady instead - when she ties them up in the boat demanding Wei Wuxian to protect her son
Jiang Clan leader - when he ties them up and asks Wei Wuxian to take care of his brother and sister
Wen Ning - nearly everything the guy did seemed to be out of pure loyalty and sentimental and funny - so can't pin point just one
Wen Qing - She takes them in despite her protests to her bro - When she disagrees with Wei Wuxian about transferring his golden core - When she says sorry and thank you before leaving Wei Wuxian
Lan Zhan - Gets drunk for the first time - receives punishment with them - when they go to cold pond cave - ties headband around wei ying's arm - they return with forged rabbit memory of their friendship foundation
Lan Zhan - After his clan has to go into hiding and Cloud Recesses gets destroyed and they break his leg
Lan Zhan still trying to stand up for Wei Ying during Wen indoctrination when the Wen irritating idiot takes him prisoner - Wei Ying offering to carry him - Lan Zhan and Wei Ying working together to get everyone off the cave - Wei Ying storing medicine for Lan Zhan and offering it to him in the cave and Lan Zhan applying it back on him
Wei Ying saves Mianmian and she leaves the Jin clan when they speak ill of him
Song Lan and Xiao Xingchen - sooo saaaddd
Wei Ying passing out and Lan Zhan sings to him
Lan Zhan warning him over and over to be careful with his demonic tricks and Wei Ying having no choice but to use it and hence promising and asking for belief that he will be able to control it - That scene outside Qionqqi way - Lan Zhan grabs Yuan when they run to Burial Mounds and takes Yuan into his clan when the others gets captured
The way Wei Ying says Lan Zhan gets me every time and the way Lan Zhan says Wei Ying gets me every time too - Honestly - Lan Zhan trying to protect him at Nightless City when he tries to take back control of the puppets with his flute and Lan Zhan catching him when he falls - Lan Zhan protecting all the time during the present - Lan Zhan carrying him back to the inn - Lan Zhan getting drunk again (the whole feeling was wow) and doing funny stuff and saying some sentiment stuff - Lan Zhan saying he had known who he was helping all along in front of everybody at Carp Tower surrounded by swords and arrows and taking Wei Ying and flying away - Lan Zhan half carrying him to Cloud Recesses - where they say to each other in their minds that it's because of Wei Ying's clear conscience - Lan Zhan puts down the sword and seals his power when Wei Ying's life is threatened by Meng Yao guy who associates himself with so many clans within the 50 episodes that it's hard to keep track whom he offended when - The few times Lan Zhan smiles - or jokes
Wei Ying's public statements - some angry, some gotcha, and some haha ones
Lan Zhan - always there to help Wei Ying's statements with the right questions or answers as the situation demands - Lan Zhan at Carp Tower feast saying he didn't hear Wei Ying ever say anything as idiotic as the idiot people there claim - Lan Zhan putting a silence spell on the Lan clan idiot (technically he was dismissed from the clan as the clan doesn't have idiot people at all, but I am still calling him that - Wei Ying is right, who remembers these idiots long enough to offend them the way they claim) (This was the most satisfying use of the spell ever from Lan Zhan instead of shutting up Wei Ying all the time)
