"the sky has no limits"

Yes, I did a post before on how Crowley's actions don’t help but exacerbate their existing problems within the student body. 

Crowley is the driving force behind the students' behaviors due to his exploitative management style.

Crowley’s actions encourage distrust of outsiders and prevent meaningful student support systems. Crowley isolates students to make them vulnerable to exploitation for his own hidden agenda 

Crowley frequently abandons the school, leaving stressed-out teens without proper adult guidance 

Crowley also constantly delegates his work to students, with the responsibility of managing the school and correcting behavioral issues entirely thrust onto dorm leaders, forcing them to overcompensate with strict, often oppressive rule enforcement 

Crowley's negligence allows a culture where students must aggressively fight to survive, demanding the student to fend for themselves drives them to desperation 

And because he leaves staff roles unfilled, even with the new book coming out, it implies that he doesn’t hire new staff, which puts strain on the teachers. His actions don’t only stress out the students but also the teachers working under them. 

This causes the students to cling to other role models to soothe their own self-loathing and insecurities 

Yes, when I think about it, that means that Crowley was planning this for the past 100 years by making the school into a breeding ground for the students to overblot. 

This could be why he allowed Azul to run his business in school on purpose; it's so he can harvest the contracts on the students' insecurities that Crowley helped cultivate for Azul to overblot.

Yes, this is a turning point for his character,

When the illusion of his mother tells him to go back to sleep, Riddle immediately assumes it's a fake because of how terrifying her real reactions were. 

Riddle conditioned himself to believe that his mother's strict, suffocating upbringing was out of love by stating she would scream at him to the point of him wishing he were dead, acknowledging the emotional cruelty of her discipline. This also shatters Riddle's illusion of her.

Ace’s character arc is about moving past his tendency to run away and learn to face his own emotions and vulnerably.

Ace is highly clever but struggles with insecurities and feelings of inferiority compared to his peers which he hides behind a playful persona which he uses to avoid having to face his emotions and vulnerability. Instead of openly admitting his anxieties he copes by deflecting and criticizing others.

Ace is known to drop out of tough situations and avoid putting any effort thinking that putting effort in something might end up risking in exposing his vulnerability 

the first indication that ace refused to face situations that required putting in actual effort is right in his backstory, in middle school Ace use to have a girlfriend but ghosted because she was “boring”, but realizes that a relationship requires actual effort but ace ghosted her mainly because he doesn’t want to put effort in a relationship he feels would put too much work. 

Book 7 addresses Ace’s habit of running away,

ace and his friends are trapped in a dream sequence created by Malleus, ace creates his own dream where he is safe and avoids the fight Ace initially refuses to fight back or try to escape revealing deep insecurity and admits to cater that he is terrified Cater calls Ace out of this and reminds Ace of his bravery during a crisis this realization prompts Ace to step up and faces his fears effectively waking him up
