At the end of season 10, Hawaii Five-0 fans got some answers but could Steve McGarrett (Alex O'Loughlin) and the rest of the 5-0 task force pop up somewhere else. The door is certainly open.
McGarrett, as most know, was a decorated former Navy SEAL, who took over the Five-0 Task Force. In accepting the job, he had one major requirement — that the task force answered only to the Governor of the state of Hawaii and would be given full immunity and means. The task force had no restrictions and was always backed by the Governor. The team was able to investigate crimes ranging from terrorism to kidnapping as well as murder and robberies.
Number two was Detective Sergeant Danny "Danno" Williams, HPD (Scott Caan). He is a divorced single father who transferred from Newark PD in New Jersey to be with his daughter.
The final season started with an agent recovering at a hospital, and that agent is thinking about moving on to other things. Other off-duty witness a murder-for-hire hit on a Chinese triad leader, but the hitman gets away. There’s never a dull moment as the show reaches for closure.
Four characters from Magnum P.I. guest starred in episode 12, which was a two-part crossover that concluded on Magnum P.I. So since that happened it’s likely characters (a lot of actors call Hawaii home) could appear in future episodes of Magnum PI or the new MacGyver.
