* CrowningMomentOfAwesome: Rob snapping at Gaby, Alex, Tina and Lenni to [[BigShutUp shut up]] in "Get the Message Part 3" when they're arguing in the park in the aftermath of the accident earlier in the episode. He really came out of his shell. It's a pity [[PutOnABus he had to move to Australia.]]
* EarWorm: The main theme: "''Ghoooostwritaaaah! '''Word!'''''"
** Don't forget the music that played whenever they rallied.
* EnsembleDarkhorse: Victor, Rob's friend in Building Bridges, seems to be very popular in the fandom. The producers must have noticed because he shows up in another episode despite not being particularly involved in the plot.
* {{Fanon}}: One of the leading theories about Ghostwriter is that he's the ghost of Jamal's great-grandfather Ezra.
* FoeYay: When Calvin tries to convince Rob [[WeCanRuleTogether to join forces with him]], it sounds like he's hitting on him.
-->"You're the strong, silent type. I like that."
** Alex even mocks to Calvin afterwards:
-->"Did you actually think that Rob would hook up with you?"
* FridgeLogic: In the "Lost in Brooklyn" episode, why didn't the girl simply call a taxi and ask her dad to pay? Well, it's easy to assume that since she was from Mozambique that she never used a taxi before and her dad forbid her from entering strange cars. That and she was 13-15, they're not always going to think rationally.
* HilariousInHindsight: There actually is a show called ''Galaxy Girl'' (well, ''Galaxy Girls'') in development by LaurenFaust.
* HoYay: Hector has a pretty blatant crush on Avatar, the male makeup artist, when the team appears in Lenni's music video.
* JerkassWoobie: Many of the villains are so pathetic that it's pretty easy to feel sorry for them. A good example is Manny Gite from "Into the Comics". He was an awkward twentysomething who lived with his aunt and desperately wanted to be a cartoonist. In an attempt to acheive this, he enters a contest for kids (in which the prize was getting to be in a comic book) disguised as his cartoon character Stoopdude and tries to sabatoge the other contestants.
* KarmaHoudini: Played With regarding Manfred Gite from "Into the Comics". Whereas most villains were taken away by the police in the end, Manfred is simply escorted away from the contest grounds after the Ghostwriter gang thwarts him. What kind of punishment Manfred got after that [[LeftHanging was never revealed]]. It's implied that if nothing else, Manfred's aunt was prepared to [[ReasonYouSuckSpeech chew him out]], but considering some of the antics he pulled were illegal, that should have landed him in jail.
* NightmareFuel: Gooey Gus.
