- Author's Saving Throw: At the end of the first Misenwood chapter, Coeur confirmed that the arc would take place over roughly three more chapters before heading back to Beacon. The readers quickly disagreed with that plan due to the arc's slow pacing, which Coeur noticed; he thus adjusted the plan and cut two chapters out of the arc, expediting the trip back to Beacon.
- Cargo Ship: Ozpin and coffee. The Chapter 18 omake in particular."Don't listen to her, Special-Coffee-Chan! She's a rival for Sempai's heart!"
- Critical Research Failure: In the beginning of the story, Coeur made a few references that implied that Team SSSN were from Vacuo. While Sun himself is from Vacuo, the rest of them and the team itself come from Haven, which he realized around Chapter 27. He considered going back and retconing it, but it only would have changed about 4 sentences in total, so he quietly dropped it and referred to them as being from Haven from then on.
- Crosses the Line Twice: Jaune slowly choking out one of the mayor's guards in Misenwood - while Neo stands off to the side giving him instructions and he's begging her to just take over already.
- Hilarious in Hindsight:
- In Chapter 32, Qrow asks if he's somehow been cursed when the population of Misenwood turns on them and attacks, but Jaune shrugs it off and assumes that he's the cursed one and Qrow just got caught in it. Volume 4 would go on to reveal that Qrow's Semblance is to cause misfortune, and he views it as a curse.
- In Chapter 33, Yang pretends that her arms are dysfunctional in order to invoke Romantic Spoonfeeding with Jaune. When they are revealed to be just fine, she claims that her professor must have Healing Hands. Come Volume 5 of RWBY, Jaune's semblance is revealed to be exactly that.
- As the two of them fight Adam, Yang jokingly suggests to Blake that they should use the "lesbian rumors" to further piss their opponent off. This is pretty much how Adam gets ultimately defeated in Volume 6 — his jealousy of Yang's relationship with Blake causes him to lose his cool and leave himself open to a counterattack from the former.
- In chapter 39, Ironwood gives Jaune a cup of his coffee, which he quickly realizes is much too strong and tastes horrible even though the General seems to like it. It's a one-off joke in this fic, but in retrospect, this is likely the first appearance of Atlesian Black coffee.
- It Was His Sled: The fact that the sequel story is called Headmaster Arc spoils the fact that Jaune becomes Headmaster at the end of the first story. From there, the fact that Ozpin is no longer Headmaster makes it obvious that the Fall of Beacon and Ozpin's death from canon still occur.
- Jerkass Woobie: Jaune is a borderline example. Considering he is using a national tragedy to con his way to a job, and keeps lying for his own gain, it would be easy to hate him. But the guilt he feels for deceiving people (especially as he starts to consider them his friends) and the moments when he thinks his cover is about to blown make you feel sorry for him.
- Moral Event Horizon: The SDC sicced the Atlas military on Faunus protestors and branded a thirteen year old Adam simply for being there.
- Nightmare Fuel:
- In Misenwood, Neo gleefully forces a man to kill himself, doing it slow enough for him to beg for his life while she sadistically laughs.
- According to Cinder, and later confirmed by Oobleck, not everyone still in the tunnels to Mountain Glenn died when it collapsed. Some were trapped in there, waiting for either their injuries, the Grimm, or asphyxiation to kill them.
- Ron the Death Eater: Coeur has made it no secret he finds Hazel and his motivations to be absolutely stupid, often deriding him as suffering Insane Troll Logic that even Salem is disgusted by. Numerous characters are given the opportunity to mock him for his motives, and he's depicted like a raving lunatic regardless of whether Ozpin is in the vicinity, taken to it's logical conclusion where he takes the position of Big Bad from Salem and tries to summon the gods back to Remnant just to finally get rid of Ozma after Salem gives up.
- Ships That Pass in the Night: Perhaps Coeurs most noted examples occur in this story, with Jaune/Glynda being teased seriously from the start and made canon, although by storys end it gets sunk when Jaunes lies unravel; theres also the Cardin/Velvet Beta Couple, which actually gets a convincing execution even withstanding the storys tone.
YMMV / Professor Arc
