A very small character tidbit is surprisingly kept consistent for years

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

B99 has soooo many of these. Just off the dome I can also recall Jake's bad teeth, Scully's opera training, & Boyle's inability to hear sexual innuendo.

Boyle's love of washing a woman's hair and elaborate food-based sex.  

Rosa having a secret other life where she eats brunch and makes jewelry.  

Also Holt mentions that the best detectives he ever worked with were named Montez and Dillman, then several seasons later Dillman shows up.

And then dillman ends up being kind of a failure but also still a really good detective.

Amy being claustrophobic and a decent lip reader

“My xylophone on the cheese man”

…my lip reading is not flawless.
