Chapter 4: Adventures in Goetia-Sitting

On her day off, Loona is made to watch over her old friend during a playdate... in Loo Loo Land.

Tropes that appear in this Chapter:

Adaptational Early Appearance: Mammon, the Sin of Greed and Fizz's employer, debuts before Fizz.
Adaptational Explanation: The reason Blitz was working as a clown at the time when Octavia was brought to Loo Loo Land was because he needed the money.
Adaptation Relationship Overhaul: While Loona and Fizzarolli have had no contact whatsoever in Helluva Boss despite their bonds with Blitz, here Loona mentions having met the clown in the past.
Affectionate Nickname: Besides 'Via', Octavia is called "Tavi" by Loona.
The Bus Came Back: Stolas and Stella make their first physical appearances since "Friends in Lower Places". Octavia also makes her present day debut.
The Cameo:
- At the beginning of the flashback, Mammon appears in an ad advertising Loo Loo Land and a Robo-Fizz.
- Emira appears in one of the reflections Loona sees in a fun house mirror.
Commonality Connection: Octavia comes around to bonding with fellow Goetian royal Cray once he says that he's come to hate Robo-Fizz, which leads to Octavia admitting she feels the same about it.
Continuity Nod:
- Moxxie is still looking for an apartment. By the end of the chapter, he finds one.
- Loona brings up making Glamour disguises for the witches.
- As the hellhound in the black hoodie watches Vox Tube videos, he sees "Lunatic Loona" is a recommended viseo.
A Day in the Limelight: Octavia is granted a chance to shine as Loona spends her day off accompanying her on a playdate with other royal kids at Loo Loo Land.
Decomposite Character: Cordelia's hellhound Bailey is essentially based around canon Loona, being completely uninvested in anything but her phone.
Expy: Hazel the shark demon is one to Witch Lezah from The Looney Tunes Show.
Given Name Reveal: Loona's twin brother is named Cyrus.
Hall of Mirrors: As she searches for Cordelia in a fun house, Loona comes across one of these, filled with magic mirrors showing strange reflections. One shows her as a cat, Emira, herself as a hellpup, and her mother before she finds Cordelia.
Honor Before Reason: Stolas offers Blitz a job working for him so he doesn't have to keep working for Shere Khan. Blitz refuses due to a combination of his pride, insecurities, and not wanting to rely on the Goetia demon too much.
Hypocrite: Loona points out that Octavia's refusal to bond with any of the other Goetia kids like Cray because she thinks they could be spoiled brats would make her a hypocrite since she herself is a Goetian princess.
Parental Sexuality Squick: After returning home from the playdate with Octavia and Linda, Loona walks in on her father and Stolas having sex and walks out to wait for Stolas to discuss learning magic from him.
The Reveal:
- Blitz and Loona met Octavia five years ago when Stolas took her to Loo Loo Land.
- Loona and Cyrus's mother died giving birth to their baby sister when they were only two years old.
- Loona met the real Fizzarolli at some point.
Running Gag: Seth the duck being harrassed by a demon goat.
Sequel Hook:
- Loona considers learning spells from Stolas.
- A hooded Hellhound sets sights on Loona.
- Amaroq is starting to become suspicious of Sonya.
Shout-Out:
- Seth being chased around by a demon goat is a reference to Reese being chased around by a goat.
- Robo-Fizz sings The Whole Being Dead Thing.
Spared by the Adaptation: Instead of being destroyed after fighting a main character, Robo-Fizz survives determined to take revenge on Loona.
Trailers Always Spoil: Loona walking in on Blitz and Stolas cwas seen in the trailer from "Friends in Lower Places".
Wham Shot: Loona goes through a fun house and sees different versions of herself in mirrors (including Emira) and comes across one showing a white hellhound; her mother.
What the Hell, Hero?: After Octavia insults Cordelia by bringing up her not having a mother, Loona (who sympathizes with Cordelia) calls Octavia out on it.
Your Mom: Irked by Cordelia telling her that Loona is spending more time with her new friends, Octavia insults her and the following argument turns into a "your mom" insult-off. It comes to an end once Octavia insults Cordelia for not having a mom.
