In a teaser released for tonight's episode, cheeky scaffolder Callum Jones receives a text, making it clear a recoupling is on the horizon.
Meanwhile, the girls in the original villa look shocked as the results of the recoupling are revealed – testing the lads' loyalty.
Clearly shocked by one result, Paige remarks: "I was not expecting that."
Though he was originally coupled up with Shaughna, Callum has wasted no time in cracking on with Mancunian model Molly Smith since he arrived in Casa Amor.
Last night, he made his feelings clear, saying: "I don't want to potentially throw something away that I think is special just because I might hurt someone's feelings in the process."
Leaning in for a snog, the 23-year-old put all of his eggs in Molly's basket.
Aware of the heartbreak he is about to cause, he said: "Shaughna's going to go f***ing mad, Everyone's going to hate me."
Meanwhile, Shaughna has been missing Callum more than ever, as she prepares to make their relationship official.
Last night, she said: "If Callum does come down on his own I will literally say to him, 'We need to have a discussion.
"If it was more official I wouldn't stress as much."
Since he left for Casa Amor, Shaughna has been plagued with doubt over their relationship, worried he was about to stray.
She said: "I just don't know what I would do if he comes back with a girl, I would not be able to live in this villa.
"I really did not think I'd be missing him this much."
How will Shaughna react when she sees Callum walk through the door with Molly on his arm?
Love Island continues tonight at 9pm on ITV2.
