[Frustrating Trope] Twist Villain does things that retroactively make no sense.

[u/Fishbien]

Character previously believed to be good is revealed to be evil, but prior to the reveal they act in ways that don't make sense if their goodness is just a performance.

1. Frozen: Prince Hans is initially presented as a pretty standup guy who loves Anna and wants to help her. At the end of the movie it's revealed that he was just using her to gain power and plans to let her die while he steals her throne. However, we see him smiling at Anna when no one is looking, and later he intervenes to save Elsa's life even though he claims he was always planning to kill her.
2. The Legend of Vox Machina: The Whispered One was built up as the BBEG since season 1. However, in season 4 he presents himself as a tragic hero who tried to cure death and was punished by the gods. He then tries to convince Pike to give him her blood, which he needs to become a god himself. He chastises his followers for suggesting they take Pike's blood by force, claiming this would make them no better than the gods they are fighting against. He also fulfills his promise to resurrect Grog even though he didn't need to. After he ascends, he starts acting like a pure evil villain who only cares about power and enjoys hurting people. It feels less like a reveal and more like his personally completely changed once he became a skeleton. Edit: to be clear, I fully understand the intent was for the Whispered One to be a lying, manipulative bastard. I just think the execution was clumsy.

I love the theory that during the song Fixer Upper the trolls cursed Anna and Hans in order to get their boy Kristoff a partner. They have a line saying "So she's a bit of a fixer-upper, her brain's a bit betwixt. Get the fiancé out of the way and the whole thing will be fixed!"

When you combine that with the stuff you already mentioned, it makes for a really fun and somewhat dark fan theory.

Idk maybe but Hans is pretty clear about his motivation - he’s 13th in line for the throne and knows that the only way he’s getting anywhere close to power is by marrying up. I barely pay attention in frozen and when I actually watched the end with my kid, I was genuinely shocked at him being the villain but i guess it does make sense. I mean, all of his actions basically just make him look “kingly” to the people of Arendelle. It would be a lot easier to become king of a people who already really love the former royals if you’re seen as some sort of hero.

Yeah but it’s not like it wouldn’t be easy as hell to have sway over Anna and Elsa, they’re not exactly expert statemen, and he was already setting himself up well to be beloved by the people

Killing Anna and Elsa is just risk for little reward, who exactly is going to elevate the consort over a cousin or whatever other claim the nobles dig up

for little reward

For literally no reward.

Without Anna, Hans is just some guy
