The episode begins with Cat and Steve having breakfast in Steve’s car. Cat is not too happy about this as she expected something more when Steve told her that they will be going someplace special; she was expecting something more romantic. Steve is trying to explain to her that this too is romantic, when a guy arrives and tries to carjack them. Guess he picked up the wrong car! Moments later the guy’s nose is bleeding and Steve hands the guy over to Duke. Steve then notices a young boy is cuffed to the table and Duke tells Steve that he is a hot head and needs some time to cool off. ..

The helicopter seen in the background in the scene where Danno & Kamekona was purchasing the black helicopter is a bit similar to the one from Magnum P.I. The showrunner Peter Lenkov is a huge fan of Magnum and was also filmed in Hawaii. Image courtesy of Book 'Em Danno on FB
The helicopter that Kamekona brought from Makani Kai helicopters is a real company set on O'ahu has been used a lot in past episodes. They also do tours around Hawaii also George Takei took one when he was in Hawaii to do the episode. Around this time of filming they've just upgraded their helicopters with elevated doors that slide across.
The diner where Steve & Catherine eat breakfast is Hawaii's Famous Rainbow Drive-In where they sell the popular Hawaiian food 'Locco Mocco' is a beef patty with rice and sweet gravy the food was also mentioned in episode 2.07 - 'Ka Hakaka Maika'I where Joe & Kensi (from NCIS: LA) was eating that was delivered by Steve at Magic Island.
The Bond 007 mention at the end of the episode contains a bit trivia about Alex.
Alex actually was in the final screen test alongside Daniel Craig for the role in Casino Royale sadly it didn't go too well and Alex hates to talk about. But look at him now.
