When "Hawaii Five-O" returns for a brand new season on Friday, we will see Steve and Catherine's relationship progressing to the next level.

The first episode of the season can be watched online at 9 p.m. ET on CBS.

The finale of CBS' drama saw the team gathering for Kono and Adam's wedding, and it featured the return of Catherine. And this could only be good news for Catherine and Steve as an Entertainment Weekly report noted that the upcoming season will see Steve planning to ask Catherine for her hand in marriage.

"Boiling him down, McGarrett is a warrior with a huge heart," executive producer Peter Lenkov told EW. "From our first season, Catherine has stolen that heart and now he's ready to take that major leap in their relationship six years later. It's probably one of the bravest things this soldier has ever done."

However, Steve and Catherine will have to go through a number of hurdles before they wed. Although it was a happy reunion, the duo did not get to have a heart-to-heart and there are many unresolved issues, which will be dealt with in season 6.

"You may have heard that Sarah Carter is coming in as Lynn, a nature lover with whom McGarrett goes on a wild adventure. Let's just say that it's going to be a busy fall for our head of Five-0," the showrunner added.

Season 6 will also focus more on Chin Ho's love life and a resolution with Steve's mom. Viewers will also get to see Danny and Steve undertaking a trip to New Jersey.

"One of the things we want to do is get McGarrett and Danny back to New Jersey," Lenkov told The Hollywood Reporter. "It's been something the fans probably have imagined, Danny taking McGarrett to his hometown."

The synopsis of the first episode of the season reads:

The team investigates a centuries-old pirate story involving buried treasure; Gabriel kidnaps Kono and Adam on the morning after their wedding.
