McGarrett (Alex O'Loughlin) and Danno (Scott Caan) have an amusing habit of getting on each other's nerves, and while we may look forward to their carguments, there are others who believe the pair need to work on their communication. In fact, their frequent outbursts landed them in mandatory counseling during season 5. Now, the pair will have to weather an entire couple's retreat during "Kuleana (One's Personal Sense of Responsibility)."

"While McGarrett and Danny attend a couples retreat in Maui to work on their partnership issues, Kamekona's dangerous past comes back to haunt him," CBS teased.

Set to air as episode 11, "Kuleana" will serve as the series' midseason premiere. With Gabriel (Christopher Sean) running roughshod over the island, Hawaii Five-0's cops could do with a little humor. Unfortunately for McGarrett and Co., McDanno's forced getaway won't remove Gabriel from the equation. Both the villain and the imprisoned Adam Noshimuri (Ian Anthony Dale) will appear in the Jan. 8 episode.
