Viewers will be able to vote on and Twitter (using the hashtags #theBoss, #theTA and #theStudent) during the broadcast. The votes will be tallied immediately and the most popular ending will be the one that airs. Separate voting will be available for Eastern/Central and Pacific time zones and all three endings will be available on CBS’ official website.  

“I’ve always felt the most fun aspect of watching a mystery is trying to figure out ‘whodunit,'” said, Executive Producer, Peter Lenkov. “Now the ‘Hawaii Five-0‘ viewers will actually get the chance to tell us who they think committed the crime and we will listen. I love that our dedicated and attentive fans will actually play a part in resolving our story.”
