The Love Island contestants are to set to face a tough choice on Friday night's episode as they vote for the least compatible couples.
Coming up, the islanders are rocked when they get a text informing them they have to vote for the two couples they think are least suited to one another. The pair with the most votes will be at risk of being dumped from the island.
Wallace and Rebecca, who have decided to remain friends, will vote tactically to stay in the villa.
For Luke the vote will be a chance to remove Mike from the show.
In Friday night's episode, Luke confronts Mike, who has started moving in on Luke's partner Jess.
Luke tells him: "There's only so much you can take. I know you're going to talk to her, but pulling her so much today..."
Mike replies: "Have I? Or has she just gravitated towards me?
"You came up mid-conversation, sat down, interrupted and then grabbed her," Luke contests.
"Fair enough, my arm was around her, the girl was cold", Mike shoots back. "You didn't provide a jacket for her, Mr Gentleman."
Jess will face the toughest decision when pushed to choose whether or not to vote for Mike and Sophie.
The islanders will also take part in the Oktobersesh challenge in which they will toss sausages, pretzels and beer at each other.
Love Island airs on Virgin Media One and ITV2 from 9:00pm.
