Ne'e aku, ne'e mai ke one o Punahoa - S10-E8
Other mistake: Five-0 discover the camouflaged crash of a Cessna supposedly carrying 170 pounds of heroin (as mentioned previously) in the jungle. The heroin is indeed discovered inside the plane, but the heroin is still neatly stacked in the back seat, even though it does not seem to have been secured. Related, a DEA agent had mentioned that there was 100 million dollars worth of heroin being brought to Hawaii. 170 pounds has a street value (according to the DEA website) of $800,000 per 20 pounds. This would only be $6.8 million, not $100 million. (00:25:30)

Factual error: The Five-0 team is discussing the helicopter incident where three people were killed. Junior states that they could find no prints or DNA at the helicopter. Yet the helicopter was full of blood, and the perpetrator (seen later) was covered with bloody wounds. It would have been impossible NOT to find the killer's DNA at the very least in the blood.

Other mistake: When a helicopter encounters a problem and declares an emergency, the pilot declares a Mayday and says the craft is N-9128R. This is false. The registration on the helicopter is shown as N-437MY. (00:01:28)
Chosen answer: They are Junior's SEAL buddies.
