Star and Ponyhead try to stop Tom from getting a "demoncism".
Tropes:
- Be Yourself: Tom willingly decides to undergo a demoncism to remove his demonic energy in the hopes of it alleviating his anger issues for Star's sake. After seeing what a demoncism did to Pony Head's ex, fundamentally changing who he is as a person, Star resolves to put a stop to it. After Tom awakens post-demoncism in agony and is told that it would just be the first session in a lengthy regimen, Star assures him the desire and effort to improve himself is the important part.
- Call-Back: Star decides to collect on Tom's corn-shake offer from the end of "Club Snubbed".
- Cannot Keep a Secret: It doesn't take much prodding for Star to get Ponyhead to blab about Tom's demoncism.
- Cooldown Hug: Star gives one to Tom when his demoncism apparently gets out of hand.
- Correlation/Causation Gag: Star is punching a tree when an explosion caused by Tom's demoncism occurs nearby. Pony Head thinks it was caused by Star punching too hard.
- Empty Shell: Unfortunately, the side effect of getting a Demoncism is that the subject is robbed of all emotion and any semblance of personality.
- Explosive Punch: Assumed; Star is angry at Tom and Marco over the former wanting to undergo a demoncism, and she leaves to go punch some trees with Pony Head cheering her on. Later, the demoncism goes horribly wrong, setting the forest on fire just as one of Star's punches connects.Pony Head: Harder! HARDER! *BOOM* ...Dang, not that hard.
- I'll Never Tell You What I'm Telling You!: How Ponyhead ends up spilling.
- Overly-Nervous Flop Sweat: Ponyhead is seen sweating profusely while resisting the effort to outright tell Star about Tom's demoncism.
- Picture-Perfect Presentation: Star looks at a video of Seahorse as a punk rocker smashing thing onstage. She then puts the phone aside to look at present-day Seahorse, a mild-mannered customer service representative with Nerd Glasses.
- Really Gets Around: When Ponyhead suggests they ask her ex where demoncisms are held, a frustrated Star asks "Which ex?" She then apologizes for sounding so harsh and judgmental about it.
- "Shaggy Dog" Story: Tom's demoncism is a success... but they were only able to remove one of the thousands of demons inhabiting him, and getting rid of them all would require a thirteen-year regimen. Tom decides it's too risky and not worth the effort.
- Ship Tease: At the end of the episode, Tom and Star end up holding hands, much to the surprise (and annoyance) of Ponyhead.
- Stepford Smiler: After his demoncism, Seahorse is left a mild-mannered doormat who cheerfully parrots customer-service stock phrases no matter what others seem to say.
- Too Spicy for Yog-Sothoth: Presumably, an average demoncism doesn't involve a giant forest fire and the ritualists running and cowering for their lives. Tom is apparently so powerful that removing his demonic energy would require a thirteen year regimen of demoncisms.
- Weirder Than Usual: Star notes this of Tom at the beginning of the episode, because it's very unlike Tom to avoid her. He's always been weird, but not like this.
