When “NCIS: Hawai’i” airs tonight, it will quietly make a bit of franchise history — via guest star Kurt Yaeger. The episode will complete Yaeger’s full sweep of all four “NCIS” editions, which is believed to be the first time that an actor has appeared on every version (“NCIS,” “NCIS: Los Angeles,” “NCIS: New Orleans” and “NCIS: Hawai’i”) in completely different roles.
