From their problems with the Yakuzza to their wedding day nuclear nightmare, Five-0's unlikely couple had their fair share of roadblocks on the way to the alter. Unfortunately, the universe will continue to rain on their parade after they finally say "I Do."

"Kono's going to have the worst honeymoon anybody's ever had," showrunner Peter Lenkov cautioned, according to TV Line. "It's going to be an interesting ride, that first episode!"

The season 6 premiere will pick up as Kono (Grace Park) and Adam's (Ian Anthony Dale) nuptials bleed into a night of revelry. Viewers won't get to see the pair exchange vows, but the duo's first dance and (hopefully uninterrupted) reception will kick off the fall run. Sadly, it seems as if their happiness will be gone in the blink of an eye.

Gabriel Waincroft (Christopher Sean), Hawaii Five-0's new big bad, may, in no small part, be the cause of the newlywed's frightful honeymoon.

"[Gabriel is] definitely going to be a force to be reckoned with, and he's going to come right up, very hot out of the gate in the first episode next season," Lenkov informed The Hollywood Reporter.
