(Note: “Pa Make Loa” from Hawaii Five-0 and “Touch of Death” from NCIS: Los Angeles are a two-part crossover. Hawaii Five-0 characters Kono Kalakaua, Dr. Max Bergman, Marku, Dracul Comescu, and an unnamed Venice Biker appear in “Touch of Death” uncredited via archive footage in flashbacks.

Dr. Noelani Cunha is recurring on both Hawaii Five-0 and Magnum P.I. so “crossover” might be a strong word here.)
