Hawaii Five-O's Steve McGarrett and Captain Lou Grover will be teaming up once more when the CBS drama returns from its midseason hiatus.

After a little coaxing on the part of the Governor, McGarrett (Alex O'Loughlin) and Grover (Chi McBride) seem willing to trust each other despite Danny's (Scott Caan) misgivings. While it might take Danno a little longer to get over the events of the season 4 premiere, "Aloha kekahi i kekahi," Grover will be putting his faith in McGarrett during the Jan. 10 showing of "O kēlā me kēia Manawa."

The episode, the title of which translates to "Now and Then," will see Grover seek out McGarrett's help when his friend disappears after apparently committing murder. As Five-O and the SWAT leader try to track down Grover's missing pal, Kono (Grace Park) will be making a rare appearance as well.

Adam Noshimuri (Ian Anthony Dale) and Kono are now able to emerge from hiding, but the former surfer must first find Adam to let him know. The last time Chin Ho Kelly (Daniel Dae Kim) heard from his cousin, she was heading up to Canada to pursue a lead, a hunch which may have proved successful since Adam is slated to appear in "O kēlā me kēia Manawa."

Hawaii Five-O airs Fridays at 9 p.m. ET on CBS.
