I get why people didn't like the new helluva boss short, but if you say something like "well we didn't get anything new/insightful to the show! No new lore"
We learnt that angelic protection/protection against demons IS purchasable in the human world implying alot of things. 1 being that a cherrub could bless an item to protect you if you've done a good deed but aren't dying OR angels can bless things and give them out, like how Versokia did with her concerts, just more ethical.
We learnt what attributes could/would be included in a sinner design and look when they get to hell, and he the way they died, what they were wearing, the obsession, personality and personal objects may affect their appearance. Giving hints to other sinner and what they could have been doing/what they looked like or their personality when they were alive.
Like Husk being the stereotype of a cat. And Niffy only having 1 eye, being a reference to how she lived, how she died or what she was like (maybe she was a on-track person in life. Never really compromising too largely or simply being a metaphor for not looking into situations more and being too naive or in this case blind to the truth)
Another thing we learnt is that Blitzo is VERY EASY to find, making the theory of the people he's killed coming back to kill him more believe and possible, as the girl from the short said that she saw his build-board. So he's definitely not hidding.
And finally, the fanfictions the girl wrote could either be foreshadowing of season 2's ending (I'd recommend Sarcastic Chorus video on it) OR it could yet again be a jab at people who look too deeply into things. Like what I'm doing now.
Being a hint that not everything should be taken seriously, and that people get so engrossed in their fanfic and theories that they actually believe it to be cannon, even when stated otherwise. Making their own interpretation only to be disappointed and made about it.
Like with the amazing digital circus and Jax thing. He was never going to be a "hot", appealing, false antagonist and re script was written for him WAY before his release so they didn't really change his character. The expectation of Jax being the main love interest got to people and many were disappointed when he came out to be EXACTLY WHAT THEY SAID HE WOULD BE LIKE
So maybe a similar situation idk
Anyways lore dump over, how's your day beautiful?
