Jin Ling demanding to see Sizhui’s baby portraits since Sizhui saw all of his. But Sizhui can only show him ones from when he was a bit older. Then Wen Ning shows up with sketches Wei Wuxian did of baby A-Yuan in the burial mounds and Jin Ling cannot deal with how cute he was.
The boys are in love, your honour.
(Sizhui and Jin Ling also realising their feelings may be more than friends and that it’s mutual when they get the painting back and the way they look at each other oh-)
Extra Footnote: Someone else did draw Wei Ying in his former life.
Cue Wei Wuxian finding under the Jingshi floorboards Lan Wangji’s drunk sketches trying to recreate Wei Ying’s face so he would never forget it during those 13 years.
