After knowing both who Jin Ling was and who his parents were, his reactions and interactions start to make more sense. Seeing him attack Wen Ning in an almost reckless manner, I originally through that it was because of what Jiang Cheng had said to him previously. But now knowing that it was Wen Ning himself that had killed Jin Ling's father, it explains his behavior. Realizing that while watching made everything more painful to continue.
Some of these realizations that I had during my first watch through might not have happened if I had an easier time remembering the names, but once I realized who Jiang Cheng was, a lot more started to fit togther. Watching Jiang Cheng's interactions with Wei Wuxian made me long for their friendly and brotherly relationship. That in itself will make the happier moments in the series hurt more than the sad ones.
Another interesting parallel present in this episode was the switch in beliefs between Jiang Cheng and Lan Wangji. The contrast from Jiang Cheng's desire to do anything to stop the Wens as well as his willingness to accept the dark arts completely changes after Yanli dies and goes to one of disdain for the dark art. And Lan Wangji's perspective goes in the opposite direction. While I never saw him in quite the extremes on either side as Jiang Cheng, he now has no qualms about Wei Wuxian using the dark arts.
Another thing that I noticed is that despite the time Wei Wuxian's smile doesn't change:
Maybe that's why he was recognized
Also I still love the flute ost. It's just so hauntingly beautiful.
