Hawaii Five-0 will get a double-barreled blast from the past before season 6 comes to a close.

'Hawaii Five-0' Season 6: Danny & McGarrett Take On A Couple's Retreat, Midseason Premiere Plot Revealed

The CBS drama closed out 2015 by filming for episode 16, and set photos reveal that two fan favorites will make a return as the events of "Ka Pohaku Kihi Pa'a" unfold. What's more, the series will get a special visit from none other than Ziggy Marley!

Odell Martin (Michael Imperioli) and Sang Min (Will Yun Lee) will both have a part to play in the spring episode, but why their characters will intersect with Five-0's latest case remains a mystery.

While neither Odell nor Sang Min were photographed inside a courtroom, snaps from actor Masi Oka (Max) reveal that someone will be on trial. McGarrett (Alex O'Loughlin) and Grover (Chi McBride) will attend the case, but it is unknown if they will merely be there as observers or if they will have to give testimony.

Chin (Daniel Dae Kim), meanwhile, will have to get wet as he and McGarrett go for a dive.

The only member of the Five-0 family not caught filming for the upcoming ep was Scott Caan's Danny Williams. Caan sits out the occasional episode in order to spend time with his family, and considering the number of guest stars writers have packed into "Ka Pohaku Kihi Pa'a," it wouldn't come as a surprise if one member of the team was lost in the shuffle.
