LOVE Island fans have worked out the 'real reason' Luca Bish backed down following his clash with Harriett Blackmore.
The pals came to blows during Monday night's visit to the South African villa.
Harriet was left furious after Luca Bish didn’t defend her during the tense game of To Be Honest.
She had previously lashed out at Casey, telling him: "Shut your f***ing mouth".
After pulling Casey to air their disagreement, he told her: "I would never be that rude to you."
As Luca and Harriett had it out, he backed down and apologised after telling her she was out of line for her behaviour.
Love Island fans at home are convinced it's because Luca has seen her soaring popularity - after she had Ronnie topped a public vote to remain in the villa.
Taking to social media, one fan said: "Anyone else find it weird that luca apologised to harriet immediately after he found out she won the public’s popularity vote?"
A second wrote: "Call me a hater but Luca changing his tune with Harriett after finding out she’s liked by the public, feels calculated to me."
"Luca switching his tune cause he realises the public actually like Ronnie and Harriet, he ain’t slick, fake ass," said a third.
While a fourth commented: "Don’t trust Luca at all hope Harriet rolls the tapes back when she’s home. That man said you changed Ronnie."
