Love Island 's Gemma Owen calls Luca Bish a "p***k" in the first row of the series, as things get heated between the pair - and some viewers think they know what has happened.
There's set to be trouble in paradise ahead of two new arrivals, as the couple clash just days after her ex-boyfriend Jacques O'Neill entered the villa.
While Luca was initially worried about what his entrance meant for them, he has since seemed reassured that Gemma and Jacques are history.
But on Tuesday night the pair come to blows around the fire pit, as it appears Gemma has done something that rattles Luca.
While details are being kept under wraps, she admits to a "mistake" and suggests there is "nothing more to it".
It's heavily hinted it is linked to Jacques - or at least that is what Love Island bosses probably want viewers to think, and it might be about something else entirely.
But something has clearly happened between Jacques' arrival and the departure of Afia Tonkmor, and fans are sure they've cracked the case.
Gemma and Luca are still in the outfits from Monday's episode so the drama has to have unfolded soon after the dumping took place.
As the clip plays out, Gemma is heard saying: "I am not..." before stopping, as the camera shows Luca rolling his eyes, clearly annoyed.
She then shouts back: "Don't roll your eyes at me you p***k, it's a genuine mistake. I'm sorry, there's nothing more to it."
Both Islanders look furious, but viewers will have to tune in on Tuesday to find out what has gone down and what it means for the couple.
Viewers think they've already worked out what has happened, taking to Twitter with one repeated theory.
One viewer said: "gemma has 10000% called Luca by Jacques name or some s**t. petty but i’m ready for it."
Another viewer guessed the same, writing: "Omg did Gemma call Luca… Jacques maybe ?!??"
A third fan added: "I’m calling it now, Gemma accidentally calls Luca Jacques."
Love Island airs every night at 9pm on ITV2 and ITV Hub.
