In tonight's show, 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”
While the girls get ready, the boys set about writing their questions for their partners.
Gabby says: “I am not excited about this challenge.”
The group then gets together for the test, with the villa watching on as each girl took their turn in the hot seat.
Gabby’s questions from Marcel include – 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?
And it seems as though Gabby’s answers throw up some drama in the villa.
Following the Lie Detector results, the girls debrief on their answers and how things stand with their boys now.
Olivia Attwood later overhears Sam Gowland telling Chris Hughes that he thinks Gabby is “fake.”
Olivia sticks up for Gabby, suggesting that Sam has just returned to the villa and is a fresh new relationship of a few days so shouldn’t be judging a couple who have been together for over a month.
Tension is fraught between the Islanders with just days to go until the end of the series next Monday.
Regardless of what Sam thinks, Gabby hatches a plan.
She gets the girls involved in her idea, asking if they’ll help her spell something out to Marcel.
Gabby then takes Marcel to the terrace for a chat – will Gabby be able to show her true feelings and will actions speak louder than words?
Love Island 2017 airs tonight at 9PM on ITV2.
