At about the 14 minute point, the Five-O team is trying to identify a bogus passenger recently arrived in Hawaii. They home in on the one passenger that doesn't make sense, "Mick St John." No raised eyebrows, nothing but the HPD cross-over stating that, "that name's about as real as a three dollar bill." Surprised no one else caught it.
I'm seeing more and more of this (I think they call it "easter eggs") showing up in all sorts of movies and TV programs. Or, maybe I've just got too much time on my hands.
P.S. - I thought the Moonlight series was very well done, and shouldn't have been canceled after just one season.
P.S.2. - I haven't even finished watching this episode, so I going to just give it an 8.
