After a two-week hiatus, "Hawaii Five-O" returns this Friday with the first of four all-new episodes that will finish off the season. A few questions remain unanswered, such as how the past might effect Adam (Ian Anthony Dale) and Kono's (Grace Park) upcoming wedding.

According to Inquisitr, we can certainly expect their wedding in the finale, but that may or may not be the case, considering everything they have gone through up until this point. For example, Kono already brought up reservations about Adams's father's business, in which he had already been busy cleaning it up. The question still remains as to where the money came from in the beginning though.

Adam had also expressed worries about her job and the amount of danger she is exposed to.

A recent article on TV Guide seemed to confirm the wedding will take place on the May 8, which is when the two-hour season finale will air. But it is also quick to pose the same question, "What will ruin their wedding?"

"Everything's quite good with that relationship," Park told TV Guide. "It's not like she's needing to sow oats with anyone. I think she finally thinks that it is a good time [to get married]."

In the next episode, according to Spoilers Guide, we will see the Five-O unit helping three married men, who wake up from a wild party night with a dead woman in their hotel room. Although they are pretty sure they did not kill the woman, they still cannot remember what they did last night, which plays upon themes common in the "The Hangover" movie franchise.

The Five-O unit will be helping them to retrace their steps in an effort to piece together the events that may, or may not, have led to the woman's death.

Meanwhile, Jerry Ortega (Jorge Garcia) witnesses a woman get kidnapped on the streets of O'ahu.

This episode will guest star Jaleel White ("Family Matters"), Pauley Shore (former MTV VJ, "Encino Man") and Kevin Farley ("Paranormal Movie").
