It was one of the shockers of the series. Fans hadn't seen it coming, but Olivia and Rykard ended up having sex in the bed next to Rachel, the night after she and Rykard enjoyed an overnight date in the hideaway.
The islanders were oblivious to their little rendezvous, but Caroline Flack later filled Rachel in on her exit from the island. Speaking about Olivia, Rachel had said: "I cannot help but think that [Olivia's] playing the biggest game in that villa."
She continued: "If she wouldn't have got with Adam to get immunity she would be out... She slept in a bed next to me and kept that from me.
"I had conversations with her about you and how happy I was, how much I liked you and she could literally look me in the eye and still know that she slept with you a day after we had that amazing night together."
Rachel told Caroline that she felt Rykard had "betrayed" her, but she did give him the chance to explain his actions. Rykard admitted if he could go back and not do it, he would never have slept with Olivia.
Proving to Rachel how much he means to her, Rykard then quit the villa in the hope of pursuing things with her on the outside.
His gesture seemed to win her over, and she told him: "The fact that you left, it does mean quite a lot... If you had stayed in there, then I probably would have never wanted to see you again. That does make me feel like this is honestly real. I really doubted everything."
Rachel and Rykard are now an official item, and proving that it's all now water under the bridge, she seemed pretty happy to be reunited with Olivia at the cast's wrap party in London yesterday.
Rykard took to Snapchat and filmed Olivia and Rachel sitting in the back of a taxi together.
The girls appeared pretty content to be in each others company, even if they did come over a little camera shy.
While Rachel and Rykard left mid-series, Olivia went on to reach the final with her now boyfriend Alex Bowen. The duo came in second place, with Nathan Massey and Cara de la Hoyde being crowned the winners.
Following the final, Olivia told fans that she is "so happy" with Alex, while he gushed that he had found himself a "keeper."
And proving just how smitten they really are, the pair were spotted kissing as they rocked up to the red carpet of the wrap party. Also in attendance were Terry Walsh and Emma-Jane Woodhams (who was bizarrely seen cuddling up to Terry's ex Malin Andersson).
Scott Thomas and Kady McDermott also put on a loved-up display, and even Javi Shephard (the villa's first evictee) was there to celebrate with everyone.
