Hawaii Five-0 might be in for a little bit of a Freaky Friday situation during the 100th episode.

'Hawaii Five-0' Major Flashback Teased, Who's History Will Be Explored?

McGarrett's (Alex O'Loughlin) Five-0 team will spend the milestone episode wrapping up the Wo Fat mystery, but TV Line reports that viewers will also see what the task force would look like if they had taken a different path.

The new scoop sheds a little light on showrunner's Peter Lenkov's cryptic teaser photo (see above). Danny (Scott Caan) and Steve seem to have swapped personalities as the New Jersey transplant drives the Camaro and dons a Hawaiian shirt as Steve rides shotgun while wearing his partner's signature shirt and tie.

Titled "If, Perhaps," the 100th episode will also put an end to any questions fans have about Wo Fat (Mark Dacascos).

"I'll tell you this: If there are any lingering questions for people who have been loyally watching the show from the beginning, they're all going to be answered in the 100th episode" Lenkov said, according to TV Line. "There really will be no more questions, as to, 'Are [Steve and Wo Fat] related?' and 'What is Wo Fat's relationship with Steve's mother?' ... That's all going to come to a head and be resolved."

The 100th episode will air on Oct. 7.
