When Che calls Ben with the results of the fingerprints, neither one presses a line button on either phone. These 5-line phones require the user to press one of the 5 line buttons. When the receiver is picked up, the light for the selected line will illuminate. The 6th, red, button places the call on hold and will cause the line light to flash and all the buttons to come up.
Five-O and HPD search the field near where Cam met his death, and locate a rock with the presence of blood on it. There is also a fingerprint which is linked by Che Fong to Jay via a criminal database which suggests that Jay had past encounters with the law. Considering how much rain is seen in the show, finding a good fingerprint on this rock, which has been thrown into the field a distance away from where Cam was killed, is somewhat far-fetched.
While the members of Five-O and the local police are searching the Faraday Ranch for the missing man, McGarrett waits with Col. Faraday (Leslie Nielsen) in the colonel's office. At one point during a shot of McGarrett speaking that's taken over-the-shoulder with the colonel sitting at his desk, the shadow of the boom microphone can be seen on the wall to the colonel's left.
