History Recap / DuckTales2017S1E3TheGreatDimeChase

* DisproportionateRetribution: According to Webby, one time the mailman brought junk mail to the house addressed to Della. Scrooge then bought the post office, and Webby claims he made the postman disappear.

* AdaptationalVillainy: Quackfaster in the comics was Scrooge's harried but overall nice secretary. Here she is an AxCrazy archivist who will threaten children seeking knowledge.
* AIIsACrapshoot: Little Bulb.

** Webby says that Della Duck is one for Scrooge. One time a mailman brought junk mail delivered to her; Scrooge then bought the post office and the mailman disappeared.

* TellMeAboutMyFather: A variant; Dewey tries to find out from Webby about Della, his mother. It turns out she's been reaching dead ends about Della for years, but with his help they go to Scrooge's private library to find it.

* JerkassHasAPoint: The Board is quite cold about the employees in the money bin, but they ask Gyro point-blank if Little Bulb will go evil like his other inventions have. Gyro can only claim that half of this inventions have gone evil. And it ends up being a valid concern.

** Gyro's last line in the episode, "Gyro ''is'' robot", and the writing on his notepad, "Project Blatherskite" heavily implies that he's going to be creating the Gizmoduck armor at some point in the future.

Louie accidentally loses Scrooge's "number-one dime" and turns to Gyro Gearloose to help him get it back. Meanwhile, Dewey and Webby become entangled in a conspiracy.

* GilliganCut / InstantlyProvenWrong: Scrooge, in an attempt to keep his board from firing everyone who works at the money bin, praises his staff. The first time, he cites the levelheadedness of Quackfaster -- then we cut to her [[WouldHurtAChild threatening Dewey and Webby with a sword.]] The second time, he tries to defend Gyro's competency...only for a now-insane Little Bulb to crash through the wall. At this point, Scrooge just flat-out tells the board that his staff is filled with loonies who would probably seek revenge on them if they were fired.

** Much of the A-plot in the episode serves as a WholePlotReference to "[[Recap/DuckTalesS2E2SuperDuckTales Super Ducktales Pt. 2: Frozen Assets]]." Louie mistakenly thinks the (false) Number One Dime is in a case because it's for use in emergencies, much like Fenton did, and goes through numerous troubles trying to retrieve it, while Little Bulb going on a rampage heavily implies that Gyro is going to build the Gizmo Duck suit in response, similar to how the GICU2 going out of control led to him creating Gizmo Duck.

* SwissCheeseSecurity: You'd think Scrooge would put his NumberOneDime under tighter security than a glass case that's easily lifted. But no, a child can easily lift and take it.
