It is not inconceivable that some individuals- especially newer fans- are unaware of that Terezi is referencing an actual work (https://archiveofourown.org/works/2427119/chapters/5371283). Seeing as it is now more or less confirmed as an intertext that should be used to interpret Dirk's character, it should be linked somewhere during Terezi's discussion with Dirk (or elsewhere on the site), so that new readers can more readily understand this connection.
