Works referencing Once More with Feeling:
- A Crown of Stars: Several lines are stealth references ("once more, with feeling"). Asuka is also told in an alternate timeline, Rei regarded her like her female role model.
- Advice and Trust: Several lines and moments reference this fic, one of the favorite ones of the author. Chihiro Tanaka is one of the classmates of Shinji, Asuka and Rei and she is also after Shinji.
- Doing It Right This Time: In this story Shinji confronts his father about the fact he is piloting the robot ate his mother. Per Word of God, it is not a coincidence. Also, like in Advice and Trust, Chihiro Tanaka is one of Class 2-A's students.
- Thousand Shinji: When Shinji is being told that Third Impact spawned thousand alternate realities, it is said this is one of them.
