Before heading into Casa Amor, Callum and Shaughna Phillips were firm favourites to win the series and bag the £50,000 prize.
As soon as the lads were whisked away from the original girls, Callum set his sights on Mancunian model Molly, sharing a bed together on their very first night in the infamous villa.
Tonight will see the lovebirds take their relationship to the next level, as Callum confesses that his head has officially turned.
Meanwhile, back in the original villa, Shaughna admits she is willing to take her relationship with Callum to the next level.
It all kicks off when she wakes up from a nightmare and recounts the bad dream to her fellow Islanders.
She says: "I had a nightmare about Casa Amor. Callum was saying to me, ‘It’s between you and another girl, but you’re completely different and the other girl’s really, really shy.'"
Later, she tells fellow contestant Paige Turley that she's ready to move in with hunky Northerner Callum.
Shaughna – who is based in London – says: "I'm ready to pack my bag and move to Manchester."
Unfortunately, in the same episode, Callum tells Molly: "I feel like when I came in here I didn't think my head would turn. I did say it would take someone special for me to turn. And I do think that could potentially be you."
Ramping up the flirting, Molly asks: "Am I making you nervous?"
Callum replies: "A little bit, it's just you."
Sealing the deal with a noisy snog, it appears Callum has well and truly dumped poor Shaughna.
Love Island airs tonight at 9pm on ITV2.
