Viewers will know that Olivia had made a play for Terry when he first arrived in the Love Island villa. At the time, she had been coupled up with Daniel Lukakis, but admitted she fancied Terry and the pair struck up a bit of a romance.
Things between them were short-lived, though, as Terry later revealed he fancied Malin. Malin then chose Terry at the recoupling and the pair have now become the villa's first official couple.
Still not 100 percent over Malin and Terry getting together, Olivia finally gets the chance to talk to Malin about the situation.
She and Malin have struck up a close friendship on the show, but Olivia had felt hurt because Malin didn't exactly have a conversation with her to reveal she had feelings for Terry too.
In scenes to air in tonight's episode, the girls are sent out for smoothies and it's not long before Olivia is quizzing Malin over "girl code."
She asks: "How do you feel about girl code?"
Malin replies: "For me girl code in my situation with Terry was to be 100% honest at the beginning, so let everybody know what's going on. As soon as that date happened we were like 'no we need to be honest'... we were seeing how we could get around it by not hurting anybody."
Olivia then says: "But then you didn't come to me, did you? I came to you. I came up to you in bed and spoke to you."
As things get slightly awkward between the pair, Malin says: "Yeah sorry I forgot about that. When I was crying? I didn't speak to anyone that day. I'd had a horrible day I was tired... I wasn't going to speak to anyone just then."
Olivia is then honest with her pal and tells Malin she was "really hurt" by her actions. She explains: "I tried to just be normal with you at first and it really hurt. It did really, really hurt. I was like, 'I'm p*ssed off... she's done this to me.' I did really, really like him."
Will the girls be able to clear the air?
