History Recap / CodenameKidsNextDoorS3E4OperationFOUNTAIN

* JerkassRealization: Number 4 when finding out why Numbuh 5 was so adamant in trying to save Leona to make up for her failure in saving a kid from the DCFDTL. This leads to him saving the team by defeating the boulder-throwing statues through dodgeball.

* SpeechImpediment: Leona cannot articulate properly since she never got her braces off.

* ArmorPiercingResponse: Throughout most of the mission, Numbuh 4 complains about why Sector V is even ''bothering'' to save "Leaky Leona" from the Delightful Children, when she's never done anything for them in the past, let alone the fact that they barely ''know'' her. Numbuh 5 snaps back at him [[MyGreatestFailure she already made the mistake of not saving a kid who was captured by the Delightful Children]], and it resulted in them doing something to him that [[ThisIsUnforgivable she's never forgiven them]], or ''[[ItsAllMyFault herself]]'', for. Numbuh 4 snarks back in response, asking what the Delightful Children could've possibly done that was so awful. That's when Numbuh 1, in dead seriousness, drops the below-mentioned WhamLine that gives Numbuh 4 his JerkassRealization.

-->'''Numbuh 4:''' Oh come on! [Leona]’s never done anything for us! We barely even ''know'' her! What do we gotta help her for?!

-->'''Numbuh 4:''' What? What did they do that was so bad?!

* {{Swirlie}}: When Leona refuses to tell the Delightful Children where the fountain is, they have Lunk shove her into a toilet which they name "Mr. Swirlie". They then ask her if she wants to visit "Mr. Swirlie's Downtown Office" (by which they mean even an even filthier toilet) and this is enough to make Leona spill. It becomes a BrickJoke when the Delightful Children fall into the fountain after Sector V defeat them in a showdown, and Leona calls it "Mr. Swirlie's Corporate Office".

** Even after TheReveal, it’s never elaborated just ''how'' the Delightful Children made Numbuh 1 permanently bald.

* BoobyTrap: The heroes face deadly obstacles in each room of the cave on their way to find Leona. It's unknown how Leona can get past these traps every tine she has to use the fountain, or how the [=DCFDTL=] dealt with them.

* ChainedToARock: Sector V find Leona tied to a pole by the Delightful Children who left her to die after she has led them to the fountain.

** Even after TheReveal, it’s never elaborated just ''how'' the Delightful Children made Numbuh One permanently bald.

* Really700YearsOld: Leona explains that she is a really three-hundred year-old woman who once discovered the FountainOfYouth and has been using it to stay a child forever.

* SpeechImpediment: Leona cannot articulate properly since she never got out of her braces.

-->'''Numbuh 5:''' Because, [[MyGreatestFailure the last time Numbuh Five DIDN'T help someone kidnapped by The Delightful Children,]] [[NoodleIncident they did something]] [[ThisIsUnforgivable she can't]] ''[[ThisIsUnforgivable ever]]'' [[ThisIsUnforgivable forgive!]]

* {{Swirlie}}: When Leona refuses to tell the Delightful Children where the fountain is, they have Lunk shove her into a toilet which they name "Mr. Swirlie". They then ask her if she wants to visit "Mr. Swirlie's Downtown Office" (by which they mean even an even filthier toiler) and this is enough to make Leona spill. It becomes a BrickJoke when the Delightful Children fall into the fountain after Sector V defeat them in a showdown, and Leona calls it "Mr. Swirlie's Corporate Office".

* VillainHasAPoint: The Delightful Children want to destroy the FountainOfYouth, believing that if news of it spread children everywhere would want to use it be young forever. Their overall goal maybe far from noble, but they may have something. The fountain's effect is temporary, and Leona has used it so much that her childhood became something of an addictive drug that she can't shake. Even if it was not, the idea of eternal youth has downsides that they don't seem to consider.

** This is the second time Lenny's face is shown since "Operation C.O.F.F.E.E".

** Numbuh 1 mentioned his baldness again since "Operation D.A.D.D.Y".
