Hawaii Five-O's McGarrett and Danno will be getting some quality bonding time, but there will be a high price to pay for it.

Is McGarrett Heading To Afghanistan On 'Hawaii Five-0'? Who Will Be Sent To Rescue A Friend?

An upcoming McGarrett/Danno-centric episode is set to leave one investigator injured while they both struggle for air.

Danny Williams (Scott Caan) has been conspicuously absent from several Hawaii Five-0 episodes this season, and that has left little time for the detective to interact with his super-solider boss. McGarrett (Alex O'Loughlin) and Danno's amusing arguments and unwavering loyalty quickly made their partnership a fan favorite and the series will honor their bond in episode 19.

"Danny and McGarrett are in a perilous situation where they have to really rely on each other, and that's a real 'blood brother' type of episode," teased executive producer Peter M. Lenkov, according to TV Line.

Mirroring last season's "Lana I Ka Moana," Danny and Steve will find themselves isolated from the rest of Five-0 when an explosion traps them in a parking garage with little oxygen, according to TV Line.

Although TV Line claims one of the pair will be injured, the site didn't specify which Five-0 member it will be. Lenkov, however, wasn't quite so skimpy on the details.

"Danno. Hurt," the executive producer ominously told one of his Twitter followers when asked what viewers should expect from episode 419.

Luckily for Danno, McGarrett's Navy SEAL skills will undoubtedly serve to keep them alive while they wait for help.

Hawaii Five-O airs Fridays at 9 p.m. ET on CBS. Click the video below to see a preview of the series' most recent episode.
