History AbortedArc / TotalDrama

* Damien and Priya's subtle ShipTease from the previous season is completely forgotten and replaced with her attraction to Caleb. In fact, Damien appears to be a ShipperOnDeck for the two.

* Leshawna falling fow Heather's fake apology in "[[Recap/TotalDramaNotSoHappyCampersPartTwo Not So Happy Campers - Part 2]]." By the next episode, she's back to hating her for unexplained reasons and Heather never bothers trying to get on her good side anymore.

* Owen and Izzy's romantic subplot came to an abrupt halt about halfway into the season due to the same order of ExecutiveMeddling that broke up Gwen/Trent and Duncan/Courtney. What makes this case stand out compared to the other two breakups was that Izzy was NotHerself when the breakup occurred, leaving it ambiguous as to whether she and Owen ever made up after she was restored to normal (whereas Trent and Gwen became AmicableExes and Duncan and Courtney became fierce enemies due to Duncan cheating on her with Gwen).

* Justin being the BigBad of the season is abandoned after Courtney debuts to the game. WordOfGod claims it was a conscious choice, as the crew realizes Justin wasn't effective enough to be the main antagonist.

* 'The season includes the short-lived love triangle between Zoey, Mike, and Anne Maria and the rivalry between Brick and Jo, both abruptly halted in the episode "A Mine is a Terrible Thing to Waste" when Brick is eliminated and Anne Maria quits the game.

* ''Action'' has Justin as the main antagonist, DJ's illegal alliance with Chef Hatchet, and Harold's one-sided friendship and attraction with Heather (which actually started as early as the post-''Island'' special). By the season's halfway point, all three of these subplots are abandoned entirely, with the first example as a result of the studio realizing too late how ineffective Justin was in this role and leading to Courtney being his hastily-chosen replacement in order to avoid rewrites (although the second is justified by DJ voluntarily quitting the game due to the alliance eating away at his conscience). Alejandro, a character that debuted in the following season, ''World Tour'', is essentially what the writers had wanted with Justin.
* Lindsay's CharacterDevelopment in ''Action'' into a more competent competitor was suddenly aborted at the very end of the season and never revisited afterwards.
* ''Action'' features a friendship forming between Heather and Leshawna after being at each other's throats for the entirety of the first season, only for this to abruptly disintegrate in ''World Tour'' and the two inexplicably returning to being bitter enemies. Similarly, Owen being brought back into the game by Chris to be TheMole in ''Action'' is completely forgotten in ''World Tour'', with Owen still maintaining his popularity and good reputation with his castmates.

* [[Characters/TotalDramaCourtney Courtney]] and Gwen's newfound friendship and the increased focus on several of the early losers from ''Island'' were abandoned mid-season in ''World Tour'' as Duncan returned to the game and started a LoveTriangle with Gwen and Courtney, leading to Noah and Tyler getting booted out of the team (Cody however remained due to his status as the object of Sierra's affections).
* Owen and Izzy's romantic subplot came to an abrupt halt about halfway into ''World Tour'' due to the same order of ExecutiveMeddling that broke up Gwen/Trent and Duncan/Courtney.

* ''Revenge of the Island'' includes the short-lived love triangle between Zoey, Mike, and Anne Maria and the rivalry between Brick and Jo, both abruptly halted in the episode "A Mine is a Terrible Thing to Waste" when Brick is eliminated and Anne Maria quits the game.
* The first half ''All-Stars'' is one long pastiche of aborted arcs, such as Jo and Lightning's continued rivalry, the Gwen and [[Characters/TotalDramaDuncan Duncan]] romance, Duncan's personal crisis and his conflict with Mike/Mal, Cameron's efforts to save Mike from Mal, Courtney and Gwen's friendship yet again, the Scott and Courtney romance, Sierra competing without Cody, Jo and [[Characters/TotalDramaHeather Heather]]'s attempted alliances with Gwen, [[Characters/TotalDramaAlejandro Alejandro]] flirting with Gwen, etc.
* The second half of the season ''Pahkitew Island'' has Jasmine's friendship with Samey (due to the latter being eliminated and then completely forgotten afterwards) and Samey trying to be her own person (dropped because [[spoiler: she tricks Amy into being eliminated in her place leaving her to pretend to be her for two episodes before being actually eliminated]]).

* Courtney and Gwen's newfound friendship and the increased focus on several of the early losers from ''Island'' were abandoned mid-season in ''World Tour'' as Duncan returned to the game and started a LoveTriangle with Gwen and Courtney, leading to Noah and Tyler getting booted out of the team (Cody however remained due to his status as the object of Sierra's affections).

* In the spin-off ''[[WesternAnimation/TotalDramaPresentsTheRidonculousRace The Ridonculous Race]]'', several teams that fell victims to the Ice Dancers' cheating, namely Crimson, Ennui, Emma and Kitty, wished that the BigBad duo would get their karma in a bad way. However, when they do get eliminated in the finale, they get no kind of punishment ([[AntiClimaxBoss or any kind of proper sendoff for that matter]]) besides being forced to watch their rivals compete against each other.

* The first half ''All-Stars'' is one long pastiche of aborted arcs, from Lindsay's short-lived participation to Jo and Lightning's continued rivalry, the Gwen and Duncan romance, Duncan's personal crisis and his conflict with Mike/Mal, Cameron's efforts to save Mike from Mal, Courtney and Gwen's friendship yet again, the Scott and Courtney romance, Sierra competing without Cody, Jo and Heather's attempted alliance with Gwen, Alejandro flirting with Gwen, etc.
