The battle for Hayley's secrets is on as The Originals continues this Monday.

Why Claire Holt Might Be Returning To 'The Originals' 

In order to save her pack, Hayley (Phoebe Tonkin) must follow the rituals of her marriage ceremony to the letter. That means revealing all of her secrets to Jackson (Nathan Parsons). Of course, there are some secrets Klaus (Joseph Morgan) will protect at all costs, including the fact that his daughter is still alive.

According to Nathan Parsons, the dispute between Jackson and Klaus will definitely lead to "physical damage" this week as the hybrid tracks down the werewolf for an epic showdown.

"It's a pretty brutal fight," admitted Parsons during an interview with The Hollywood Reporter on Friday.

Impulsive and merciless, Klaus won't waste any time this week in picking a fight with the fiance of his daughter's mother.

"It's going to be good," Parsons insisted. "I'm very excited for people to see this battle looming between Klaus and Jackson. We're going to see a truer side to both characters in that, so I'm looking forward to it."

While much of the conflict about this truth ceremony has centered around Hayley's secret, Parsons assured fans that Jackson has a few skeletons in his closet too. He knows things about Hayley's family that she might not be ready to accept so easily.

The Originals continues on The CW with its second season on Mondays at 8 p.m. ET/PT.
