In this evening's episode, Gabby gets a text: “Islanders, it’s the moment of truth. Girls, you’ll be taking a lie detector test. Boys you will be asking the questions. #hometruths #truthhurts #polygrafting”
The girls are worried about the impending Lie Detector test while the boys prepare their questions in the garden for their partners.
Jamie Jewitt quizzes Camilla with questions including Is Jamie a good kisser? Are you looking forward to seeing how things go with Jamie on the outside? Would you say Jamie was everything you look for in a man?
When asked Do you think you and Jamie are compatible?, Camilla says yes but the lie detector says it's a lie.
Camilla cryptically remarks: "The sad fact is I know exactly why I don't believe that Jamie and I are compatible."
Last up is Gabby with questions from Marcel Somerville including – Are you with Marcel because he is in The Blazin’ Squad? Can you see a long term future with Marcel? Do you genuinely love Marcel?
Like Camilla, Gabby is told she is lying in this preview clip from tonight's show and Marcel's face is a picture.
Elsewhere in the task, Olivia gets angry at Chris for his questions in the test.
Chris asks Olivia: Do you trust Chris? Do you see a future with Chris? Do you really want to be Chris’ girlfriend? Do you really love Chris?
Meanwhile, Amber's questions from Kem include Do you trust Kem? Do you genuinely feel you love Kem? Is Kem the best you’ve ever had in bed? Do you feel ready to be loyal to Kem for the foreseeable future?
Georgia is asked by Sam – Do you see a future with Sam outside the villa? Would you be tempted by other boys on the outside if you were together?
And finally, Montana is asked and Alex: Do you feel love towards Alex right now? Will you be tempted by boys on the outside world?
