When Penguin gets out, Batman keeps a close eye on him, convinced that his apparently innocent activities are a front for some new criminal scheme.

The story ends with Batman unsuccessfully trying to convince the parole board not to send Penguin back to prison.

After this point, it's Mittens who thinks Penny's love for Bolt is sincere, and Bolt believing that it wasn't.

- During the run of Roseanne, the characterizations of Becky and Darlene almost completely reversed through the course of the seasons. Early on, Becky was a high-achieving straight "A" student whereas it was considered a major accomplishment if Darlene could keep a "C" average and once used the excuse that the reason she skipped one class was because her friend forgot to wake her up after another class. However, as the girls got older, Darlene entered college and became a very successful student and creative writer whereas Becky completely dropped out of school to get married and ended up living in a trailer.
- Dr. Quinn, Medicine Woman seems to have an example of this at first glance. Sully is generally more progressive than most of the other men in town about almost every issue: ethnical minorities, women's rights, controversial books in the new town library, the theory of evolution, homosexuality... But when it comes to the railway and other building projects, Sully is the one fighting "progress" and the other men are supporting it. It becomes a subverted case though: Sully has good reasons to dislike that kind of "progress", because he knows how this would affect the local Cheyennes, all the animals in the nearby forest and the nature scenes. Which would have been a radical viewpoint in the 1860s/1870s. The other men on the other hand will only want to make a quick profit, and will not care too much about if other values could be lost. So it means that Sully still is the progressive one and the other men the more conservative ones.
- A variation occurs on Friends. After Rachel and Phoebe's apartment is destroyed in a fire, they must live with their friends with one living with Monica and Chandler and the other living with Joey. Monica's is seen as the better option due to its cleanliness and her tendency to spoil guests while Joey's is an unkempt pigsty. Eventually it's decide that Phoebe will stay at Monica's and Rachel with Joey. However, Phoebe gets frustrated by Monica's rules for keeping the apartment clean and the constant attention. Meanwhile, Rachel actually enjoys living with Joey because she can be as untidy as she wants and has fun playing games with him that make the apartment messier.
- The titular character from Lady Windermere's Fan thinks Mrs Erlynne is a wicked woman; her husband, however, thinks there is good in her, allows her to blackmail him because he thinks she deserves another chance, and has her at the house as a guest against his wife's wishes. Mrs Erlynne's act of saving Lady Windermere from disgrace at the cost of her own second chance in society reverses the situation: Lady Windermere is deeply grateful to her, and is forced to dispense with her previous black-and-white worldview; her husband, having witnessed Mrs Erlynne disgracing herself in a gentleman's chambers after all he's done for her, considers her beyond the Moral Event Horizon. He comes around, though.
- In Pokémon Black and White, Cheren is concerned with To Be a Master, analyzing every opponent he meets to give him an advantage, while Bianca is somewhat aimless and clumsy in her battles, becoming a Trainer largely to try to figure out what to do with her life. By the end of the game, Cheren has reached a roadblock and is questioning if he even has the personality to be a champion, while Bianca comes to terms with her father, who didn't want her going into the dangerous world on her own, and has decided her path for her future, assisting Professor Juniper in the lab.
- It's subtle, but this a major theme in Final Fantasy X and its sequel, Final Fantasy X-2. In the first game, Tidus (the protagonist) is a selfish, wangsty teen who is more concerned with returning home than the imminent destruction of Spira. It isn't until he learns that his Love Interest (Yuna) will have to sacrifice herself to defeat Sin that he starts to undergo Character Development and refuses to let Yuna sacrifice herself to save the world. There's a conversation roughly a third of the way through the game which highlights their different philosophies, in which Tidus questions whether sacrificing your life, even when the Big Bad is sure to come back is worth it and Yuna disagrees and says she feels any sacrifice is worth bringing just a little happiness to the world. In the end, Tidus has to make a Heroic Sacrifice himself in order to destroy Sin and break the Vicious Cycle, devastating Yuna, who had been prepared to sacrifice herself, but not her loved ones. Then, in the sequel, Yuna is a Heartbroken Badass Action Girl whose perspectives on sacrifice have completely changed. When another character offers to sacrifice himself in order to defeat the new Big Bad, Yuna shoots his plan down immediately, stating how much she's grown to hate having to "lose in order to win". To make this juxtaposition even more poignant, Yuna's outfit throughout the second game is a direct homage to her dead love.
- The Alliance in World of Warcraft has hotheaded King Varian Wrynn and pacifist Lady Jaina Proudmoore. Varian has had a troubled history with the Horde and along with Warchief Garrosh Hellscream are the main reasons why the two are at war now; while Jaina is leader of Theramore, and worked with then Warchief Thrall to fight against the Burning Legion in Warcraft III. As of Mists of Pandaria, Varian has grown into a Reasonable Authority Figure and no longer views the whole Horde as evil, just specific elements like Hellscream. Meanwhile Jaina saw Theramore destroyed by a Horde attack, and needed to be talked down before she tried to destroy Orgrimmar; then she was made leader of the neutral city of Dalaran, believing that it remained a beacon of hope for mending Alliance/Horde relations, until the Horde used it as a jumping point to invade Darnassus, which has broken her faith completely.
- XCOM: Enemy Unknown put the player in charge of a globally-supported XCOM, backed and funded by a coalition of nations across the world, fighting against a secretive and subversive alien threat. The 2016 sequel, XCOM 2, is set in an Alternate Timeline of sorts (it's tacitly assumed that the ending you almost certainly got in your first playthrough is canon) where all human resistance including XCOM was annihilated by the invading aliens, who consequently put the earth under Advent, a sinister pro-alien government - XCOM lives on as an underground movement painted as traitors and terrorists by Advent propaganda, and leading the fightback. This extends to gameplay - in the original, your troops had to seek out and destroy alien forces hidden on the map, whereas in the sequel, it's your XCOM troops who are hidden and the aliens enemies are the ones standing in plain sight, just begging to be ambushed.
- There's an Arthur, King of Time and Space space-arc strip that starts with Lancelot claiming that God made the universe to be perfect as it is, and Guenevere countering that change is good, because it's how things progress. Arthur tells Merlin he wishes they could see things from each others' perspective. The next panel has Lancelot saying that if a certain species is dying it's God's will, and Guenevere responding that on the contrary, things have to be preserved.
- In General Protection Fault, Nick starts a Wide-Eyed Idealist who is also prone to trusting people he shouldn't, like he does with Trudy. By contrast, Ki is far more hesitant to trust people and dislikes and distrusts Trudy from the beginning. After Trudy's plans are thwarted in the Surreptitious Machinations arc, Nick feels guilty about having been blind to Trudy's nature, while Ki admits that there is some good in Trudy, since she couldn't bring herself to kill Nick even after he rejected her. Some time later, when faced with the issue of whether to trust Trish in spite of several red flags, Nick refuses to trust her based on his experiences with Trudy, while Ki wonders if Nick is right and she should trust people more, deciding to trust Trish. After the two reach their conclusions in this strip, Nick lampshades it with the above quote.
- The SCP Foundation verse is rife with these, both within individual SCP's and tales and in the broader lore, but one of the most shining examples is the Church of the Broken God. Once the CotBG was seen as a zealous cult of Machine Worshipers and the Foundation as the only group preventing them from initiating an apocalypse out of blind adherence to doctrine. Several years of plot development and lore exploration later, however, and there is a growing possibility that the Foundation's blind adherence to the doctrine of contain first, dissect and ask questions later, has been crippling the keepers of humanity's only weapon against one of the greatest threats the foundation has ever known.
- In one episode of Dexter's Laboratory, Dee Dee crushes a bunch of ants, because she thinks they're filthy.

- The New Adventures of Winnie the Pooh has the episode "Tigger Got Your Tail," where Tigger leads Pooh and Piglet on a hunt for invisible "Nobodies" who have been stealing things. Rabbit dismisses this as nonsense, claiming "There's a reasonable explanation for everything"...until his vegetables starts disappearing. At the end, when everything is recovered (crows were stealing the vegetables, Piglet's painting had blown away, and Tigger had just lost his voice), Pooh tells Rabbit that he was right...but poor Rabbit is so frazzled that he's still babbling about "Nobodies."
- The modern Canmore siblings in Gargoyles. Initially, Jason and Robyn were determined to wipe out the gargoyle species completely, while Jon was only interested in fighting Demona in particular and was even willing to consider allying with the Manhattan Clan against her. By the end of Hunter's Moon, Jason and Robyn realized that their vendetta against all gargoyles had done more harm than good, but Jon had decided by then that all gargoyles were evil.
- South Park's "About Last Night" takes place right after the 2008 presidential election. Barack Obama's supporters are jubilant, believing his win has instantly solved all of their problems and begin to get drunk and party while John McCain's supporters are convinced that Obama's win is a sign of the apocalypse and either kill themselves or hide away in shelters. The next day, everything is still the same and society has not changed one bit. The McCain crowd realizes they overreacted and decides that maybe Obama won't do such a bad job while the Obama supporters, angry to find out they still have responsibilities and they must pay for their drunken actions, complain that Obama lied and wish they voted for McCain.
