"Buddy cop show" is a common trope; but so is a partnering of a cop and a civilian, and especially a cop and an extraordinary civilian (a mentalist in The Mentalist, an immortal in Forever, a fallen angel in Lucifer, a blocked writer in Castle, a tattooed amnesiac in Blindspot, a mnemophage in iZombie, etc.). Is there a common name for this trope? If not, what would be a succinct way to describe it?
Originally posted to English SE. Cop and Scientist from TVTropes was proposed and seems to awkwardly fit, but in many of these the partner is not a scientist (Mentalist, Lucifer, Blindspot, Castle), or is not primarily used for the scientific expertise (iZombie).
