Here's some little details in JoC and tMoN that I really like
There's a false credit roll in JoC after Gallerian burns away in the mansion which is interrupted by the slam of a gavel, more specifically, his gavel. He won't let his story end even in death, and he wants to be the one to pass the final judgment on himself.
JoC ends in an abrupt pounding of a gavel. The instrumental of TMoN ends with Nemesis firing the bullet, but after that there's a prolonged silence with her final line. Nemesis is alone again.
The irony of Nemesis calling Gallerian "son of a bitch", unknowingly insulting Ma.
The HER in MOTHER being in red.
In the frame of Nemesis pointing a gun, her left eye is covered, alike how Gumillia's mask is missing an eye and Gallerians eye in his iconic 👌image has a shadow over his eye. I think it partly represents blind justice. But blind justice is having both eyes covered, so their justice still has bias with their right eye not being covered. It also represents the eye of Horus.
The cover on Nemesis's left eye disappears when she has made her decision to kill Gallerian. Both her eyes are also covered when she's asking him to hand over his fortune.
Nemesis mask is essentially the blindfold the goddess Nemesis wear.
The strings of coloured light when Gallerian falls to hell being all the vessels he collected.
I don't this means anything, but the songs are almost the same length. Nemesis is just a few seconds longer: 5:01 , 5:04
At the start of JoC, the background colour is changing in between yellow, orange and pink. Not sure if it means anything but worth to point out?
The soft instrumental in JoC when Gallerian is with "Michelle".
When Gallerian has his eyes open, "Michelle" had them closed, and when Gallerian closes his eyes, "Michelle" had them opened - showing the two different realities inside the delusion.
