History Recap / OddSquadS2E35OddsAndEnds

* TheLastOfTheseIsNotLikeTheOthers: As the Big O hands plates with macaroni art creations of his to the Main 4, he punctuates each award with the fact that he made it...except for Otis' award, which was found, not made.

* DarkerAndEdgier: While [[Recap/OddSquadS1E40OIsNotForOver "O is Not For Over"]] did feature Odd Todd manipulating Otto and attempting to drive a wedge in his and Olive's friendship, a climactic battle at the end that resulted in Headquarters nearly getting fully destroyed, and a RankUp with Olive and Otto becoming Directors, the episode is ''very'' tame compared to this season finale (both [[Recap/OddSquadS2E34WhoIsAgentOtis "Who is Agent Otis?"]] and this episode) and its dark shift in tone. Of note, Ohlm, the BigBad, has an ultimate plan to build a black hole out of ''every single gadget in Precinct 13579's possession'' in order to create a black hole with enough power to ''suck every Odd Squad agent into it and kill them,'' up to and including himself. It definitely wouldn't be the last time the show would veer into this territory either -- the Season 3 finale is also very dark compared to other episodes in the season as well as [[Recap/OddSquadS1E40OIsNotForOver "O is Not For Over"]].

%% * GettingCrapPastThe Radar: Due to overwhelming and persistent misuse, GCPTR is on-page examples only until 01 June 2021. If you are reading this in the future, please check the trope page to make sure your example fits the current definition.

* SurpriseCreepy: The episode takes a turn into being outright creepy at one point, with Oona whispering for Olympia to meet her in the lab followed by the two agents ducking under one of the lab's countertops with unsettling looks on their faces.

* OffModel: After Ohlm walks off with all of Olympia's gadgets, Oona says "Orchid?" as she performs OffscreenTeleportation and appears next to Olympia, instead of Olympia's name, which would make more sense.
** The Main 4 are shown willingly backing up into a nearby wall as Ohlm fires a gadget that has the ability to create enlarged banana stickers, which would play the trope of CapturedOnPurpose straight despite the writers likely intending the Main 4 to be caught against their wills.

* MediumAwareness: The CouchGag in the opening theme has Olympia saying that "this is the end of our story". She's not wrong, as this episode marks the final appearances of her, Oona and Otis. [[note]]Olympia would go on to make a brief appearance in an [[CharacterBlog [=OddTube=]]] Season 2 episode with Orla as host, but only her voice is featured. Oona would also go on to make voice-only appearances in the [[{{Podcast}} Odd Squadcast.]][[/note]]

* PutOnABus: A lot of agents from the past two seasons board the bus, save Orchid and Coach O. Otis also boards the bus and is never seen again after this season, while Olympia would get a vocal cameo in Season 2 of [[CharacterBlog [=OddTube=]]] with Orla as host and Oona would get a vocal cameo in a couple episodes of the [[{{Podcast}} Odd Squadcast.]]

** Apparently, [[Recap/OddSquadS1E40OIsNotForOver Ohlm isn't the only one]] who tells people to [[ItIsPronouncedTroPAY pronounce his name right]] -- it runs in the family, as his father does it as well.

* ItIsPronouncedTroPAY: Mr. Ohlm tells the Main 4 that his first and last name is pronounced "Ohlm". Olympia in particular doesn't get it.

* GettingCrapPastTheRadar: The TropaholicsAnonymous implication of Todd's Home for Villains aside (which is going a step further for being a Creator/PBSKids show), Ohlm states that there are three reasons anyone does anything: for [[LoveHungry love,]] [[OnlyInItForTheMoney money,]] or [[DrunkWithPower power.]] While going through the list, he states that love "gives you the cooties".
** Like Todd did in [[Recap/OddSquadS1E24TrainingDay "Training Day"]], Ohlm attempts to murder his fellow co-workers -- only this time around, he does so with a far more realistic and serious threat: a black hole.
** Ohlm scratching and sniffing the banana sticker trapping the Main 4 has a few...disturbing implications.

* TheCameo: Olive, Otto and Oscar, as well as all of the agents present in Seasons 1 and 2, make cameos as pictures that the Main 4 put up when deducing who is sabotaging Precinct 13579. Funny enough, all of the pictures of agents used are from the now-defunct Wall of Agents section of the Odd Squad website.

* PutOnABus: A lot of agents from the past two seasons board the bus, save Orchid and Coach O. Otis also boards the bus and is never seen again after this season, while Olympia would get a vocal cameo in Season 2 of [[CharacterBlog [=OddTube=]]] with Orla as host and Oona would get a vocal cameo in the first episode of the [[{{Podcast}} Odd Squadcast.]]

* MediumAwareness: The CouchGag in the opening theme has Olympia saying that "this is the end of our story". She's not wrong, as this episode marks the final appearances of her, Oona and Otis. [[note]]Olympia would go on to make a brief appearance in an [[CharacterBlog [=OddTube=]]] Season 2 episode with Orla as host, but only her voice is featured.[[/note]]

* PutOnABus: A lot of agents from the past two seasons board the bus, save Orchid and Coach O. Otis and Oona also board the bus and are never seen again after this season, while Olympia would get a vocal cameo appearance in Season 2 of [[CharacterBlog [=OddTube=]]] with Orla as host.

* DudeWheresMyReward: The Main 4 risk their life to stop a villain from creating a black hole and killing everyone who gets sucked into it. What do they get from the Big O? Plates with macaroni art.

* TheCameo: Olive, Otto and Oscar, as well as all of the characters present in Seasons 1 and 2, make cameos as pictures that the Main 4 put up when deducing who is sabotaging Precinct 13579. Funny enough, all of the pictures of agents used are from the now-defunct Wall of Agents section of the Odd Squad website.

* AnswerCut: As Owen instructs his fellow Security agent to take Otis' and Ms. O's things to Todd's villain rehab center, Olympia wonders why the two ex-agents are there. Transition to Todd leading Oprah and Otis down the stairs of his Home for Villains.

--> ''Oona:''' Thank you, ma'am.

** Olympia, Otis and Oona also complete Oprah's "Well, what are you waiting for?" {{Catchphrase}} by them, as well as Oprah herself, say "Go!" in unison.

* CallBack: Ms. O brings up how Ohlm was partnered with Otto in the [[Recap/OddSquadS1E40OIsNotForOver Season 1 finale.]]

* DarkerAndEdgier: While [[Recap/OddSquadS1E40OIsNotForOver "O is Not For Over"]] did feature Odd Todd manipulating Otto and attempting to drive a wedge in his and Olive's friendship, a climactic battle at the end that resulted in Headquarters nearly getting fully destroyed, and a RankUp with Olive and Otto becoming Directors, the episode is ''very'' tame compared to this season finale (both [[Recap/OddSquadS2E34WhoIsAgentOtis "Who is Agent Otis?"]] and this episode) and its dark shift in tone. Of note, Ohlm, the BigBad, has an ultimate plan to build a black hole out of ''every single gadget in Precinct 13579's hands'' in order to create a black hole with enough power to ''suck every Odd Squad agent into it and kill them,'' up to and including himself. It definitely wouldn't be the last time the show would veer into this territory either -- the Season 3 finale is also very dark compared to other episodes in the season as well as [[Recap/OddSquadS1E40OIsNotForOver "O is Not For Over"]].
* DefiantToTheEnd: Ohlm absolutely ''refuses'' to stop until Odd Squad as an organization is at its knees. Oprah stops him herself...by taking him straight to his parents.

** Ohlm also states that as an Odd Squad Director, he's in a position to take Odd Squad as an organization down for good. However, he apparently doesn't factor in the Big O, who is higher in rank than him -- meaning that if Ohlm wanted to take Odd Squad down, he'd need to somehow defeat the Big O (and his lackeys) to succeed.

* TheFellowshipHasEnded: This is the last episode to feature the Main 4 of Season 2 -- with Oprah being promoted to the Big O, it's just Otis, Oona and Olympia that remain at Precinct 13579, and Oprah joins Opal, Omar, Oswald and Orla next season to make a Main 5 group for Season 3.

** During one of Ohlm's [[{{Flashback}} Flashbacks,]] a nearby Hilton hotel is seen, making this one of the rare few brands to not be covered up by the [[BrandX Shmumbers brand]] in some way.

** Like Todd did in [[Recap/OddSquadS1E24TrainingDay "Training Day"]], Ohlm attempts to murder his fellow co-workers -- only this time around, he does so with a far more mature-themed threat: a black hole.

** Brother Quack also pulls one near the end of the episode, as he apologizes to Otis for his actions and reconciles with his adopted son.

** Ohlm later plays the trope straight when Oona worriedly mentions that gadget #10,100 is the Black-Hole-inator, only for him to ask if she can speak up since there's a bad echo in the airplane hangar.

* IdiotBall: Oona juggles it consistently throughout the episode -- sometimes she'll have moments of intelligence, and sometimes she'll be a complete idiot.
* IKnowWhatWeCanDoCut: When Ohlm refuses to give up in his mission to destroy Odd Squad, Ms. O says that there's only one thing left to do. Cut to Ohlm's house, where his parents react in surprise when told what he's done.

* ItsAllMyFault: Orchid's constant belittling of Olympia and how she got Oprah and Otis fired from Odd Squad causes her to kick herself over them being fired, even quoting the trope name verbatim at one point as she thinks that the precinct is destroyed.

* KidsPreferBoxes: It's revealed that the only possession Otis has is a cardboard box. (Perhaps it served as a nest for him to replace the one he used to sleep in.)

* LazyBum: Owen, by ''God,'' Owen. While it's well-known that he goes on break often, this episode reveals that he goes on break for ''entire days'' at a time, or what is known to many as "taking a day off". Even ''Oprah herself'' realizes that she needs to reprimand him properly.

* MediumAwareness: The CouchGag in the opening theme has Olympia saying that "this is the end of our story". She's not wrong, as this episode marks the final appearances of Oona and Otis (but not Olympia, as she would make an appearance in an [[CharacterBlog [=OddTube=]]] Season 2 episode with Orla as host).
* MotiveRant: Ohlm goes on one when Ms. O asks him why he turned against Odd Squad. However, special mention goes to this gem of a line that he gives the Main 4 before he launches into his motives.

* MusicalNumberAnnoyance: Otis and Oprah are mostly left confused by the VillainSong that Todd and the other ex-villains sing, but when Todd tells them to sing a song about their feelings, Oprah is ''not'' happy and lets out one of her sharp trademark growls.

** The show also has a variant of the trope, only with any words related to a lack of intelligence like "dumb" or "stupid" rather than death-related words and phrases -- the episode, and by extension the show, goes to ''incredible'' lengths to avoid using those two words in particular, with the go-to phrase being "not smart" or some variation of it (although "fool" is slipped in a few times). This seems to be network policy for Creator/PBSKids, as other shows follow the same rule when it's applicable.

* NowThatsUsingYourTeeth: Since he's using his arms as wings, Otis grabs gadget #5 with his teeth, deactivating the Black-Hole-inator.

--> '''Ohlm:''' I feel like you're right.

* RiddleForTheAges: Odd Squad agents apparently don't get paid, making the mystery behind how they can support themselves financially grow even further.

* SeriesFauxnale: This episode has Oprah being promoted to the role of the Big O and has her presumably leaving the show for good, going to work at the Big Office in the previous Big O's stead, which would make her the last remaining member of the original Main 4 (out of Olive, Otto and Oscar) to leave the show. It also ends on the Season 2 Main 4 going to fight oddness one last time before Oprah's departure. However, Season 3 was greenlit 2 months after this episode premiered in the United States, and as a result, the show was retooled to include Oprah as the Big O in a core cast of 5 agents instead of 4, along with a set and theme change to "breathe new life" into the show, according to Tim McKeon.

* SupremeChef: Oona has the ability to bake cakes. How big she can make them, though, depends on the flavor -- in the case of vanilla, it's about three layers tall.
--> '''Ms. O:''' When you said huge...you were right, Oona.

* TrojanHorse: The Main 4 have one in the form of a cake that Oona has baked, with Ms. O and Otis inside of it. However, they don't use it for attack purposes, but rather, they use it to sneak Ms. O and Otis into Precinct 13579.

* UnrealisticBlackHole: Ohlm manages to create the Black-Hole-inator using every single gadget in Precinct 13579's arsenal. It doesn't look like your average black hole, and Ms. O and Ohlm prevent themselves from flying into it by holding onto a floor vent. Oona also prevents herself from flying into it via her armor suit; meanwhile, Olympia and Otis aren't affected at all, even when the latter flies close to it to retrieve the gadget needed to turn it off.

--> '''Ms. O:''' Unless...[[ObfuscatingStupidity he was only pretending not to be smart.]]

* YouthIsWastedOnTheDumb: The Big O is a child that is younger than a majority of, if not all of, the agents at Precinct 13579 -- and yet, he names Ohlm, known for being [[TheDitz incredibly stupid,]] as Ms. O's successor, despite him saying that there are many who are more than capable of being a competent Director. Why does he do this? Because Ohlm gave him an ''action figure.'' This promotion benefits virtually no one but Ohlm himself, as he is revealed to the BigBad whose new position allows him to move forward with his EvilPlan. Once the Main 4 defeat him, the Big O names Ms. O to be ''his'' successor.
