They also play with this trope, where a character who was just introduced that episode is about to die, and she goes “Now I’ll die before solving my twin sister’s murder, the whole reason I became a cop. It’s my origin story!” To which another cop says “Debbie, there’s no way you’ve ever mentioned that.” One of my favorite one-off characters.
