Check Out Jerry's Terrifying Halloween Costume on Hawaii Five-0

Get a sneak peek at the Halloween episode

Liz Raftery

Danno's playing bad cop this Halloween -- with his own daughter.

On Friday's episode of Hawaii Five-0, Danny (Scott Caan), recalling that Grace (Teilor Grubbs) snuck out to go to a Halloween party last year, puts her under house arrest for this year's holiday. She's only allowed to leave the house to go trick-or-treating with her younger brother Charles (Zach Sulzbach). As Danny puts it, "Don't do the crime if you can't do the time."

But like any good cop, to make sure Grace doesn't disobey him like she did last year, Danny puts eyes and ears on the ground. That would be Jerry (Jorge Garcia), whom Danny recruits to be babysit. And while his gruesome costume evokes only an eye-roll from Grace, it seems pretty guaranteed to scare Charlie into submission.

Watch the video to get a sneak peek at the Hawaii Five-0 Halloween episode.

Hawaii Five-0 airs Fridays at 9/8c on CBS.
