Meaningful Echoes in fanfiction.
- In chapter eighteen of Harry Potter and the Guardian's Light, Voldemort does a dark take on "you look so much like your father, but you have your mother's eyes."Voldemort: Well there's an interesting look. So... fierce. No fear like before. Reminds me of your father. [chuckles] Yes, you've no doubt been told that you have your mother's eyes. Even I noticed, and I didn't even know them that well! Of course, it's hard for me to forget the details of the night I died. Anyway, it is true that you have your mother's eyes, but that look... that look is your father's. It's the same look he had right before I killed him. Defiant until the end, he died like a Gryffindor. He died like a fool.
- Happens several times in Kyon: Big Damn Hero, most notably after the student council calls Kyon to question him for fighting in the high school grounds.Kyon: I don't really believe that last part, but it's nice of you to say. I just want to point out, though, that a challenge against any one of us is a challenge against all of us.
Haruhi: [after barging in the room] Trying to pick us apart by calling out my underlings when I'm not around, eh? Well, you've got a lot to learn! A challenge against one of us is a challenge against all of us!
- In Luminosity, Bella tells a person who wants to be a vampire that being bitten — which is a requisite for turning — is "not fun".

At the climax of To Forgive Is Equine, she says it again, only this time it's in a much more heartwarming context as it's to mentally prepare herself to perform an extremely difficult spell which, at this point, is the only thing that can save Twilight Sparkle's life. Her stage name even becomes this whenever it's said after we know where she got it. It was her deceased father's pet name for her and a way to dedicate her shows to his memory.
- The Back to the Future fanfic "Almanac Chronicles" ends with one from a quote from the Alternate Timeline from the trilogy's second movie.

- An example similar to the second listed echo for Naruto happens in doujin, in which Kakashi reflects on his ninja career, and believes that he failed to adequately instruct Sasuke and pass on his teacher, the Fourth Hokage's example. Naruto then repeats his line about not letting his comrades die, causing Kakashi to realize that he may not have gotten through to Sasuke, but Naruto is following his example.

- There are a number of recurring phrases in Those Who Stand for Nothing Fall for Anything, due to Light Yagami's Lemony Narration, which is dotted with catchphrases and Brick Jokes. One of these is his insistence that he only smokes socially - "My doctor doesn't even consider me a smoker." He says this at least three times where it's Played for Laughs, being one of the most obvious details where he serves as an Unreliable Narrator. Then, toward the end of the story, after Light has mostly completed his descent into madness, he throws out this quick line:Light: ...My doctor says I should stop smoking now.
