An upcoming injury will lead to a bit more quality time for Hawaii Five-O's Steve McGarrett and Danny Williams.

With their witty repartee and opposing views on what is an acceptable level of danger, McGarrett (Alex O'Loughlin) and Danno (Scott Caan) quickly solidified their place as fan favorites following the CBS drama's reboot. Unfortunately, the duo have been working separately for a large portion of season 4.

Viewers were grateful to get a McGarrett/Danno centric episode with "Nā hala a ka makua (Sins of the Father)" and many will be pleased to hear that the partners will be the focus of episode 419.

"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," said executive producer Peter M. Lenkov, according to TV Line.

Although the partners have had such bonding episodes in the past - such as the time they spent adrift in the ocean during season 3 (see video below) - but this time Danno will be in more danger than usual.

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

With McGarrett's Navy SEAL training, however, Detective Williams should be in good hands.

Hawaii Five-0 airs Fridays at 9 p.m. ET on CBS.
