Right now five couples remain: Chris and Olivia, Kem and Amber, Alex and Montana, Jamie and Camilla and Marcel and Gabby.
In tonight's episode, as night falls, the Islanders raise a glass to the final 10 Islanders.
But then a shock text arrives.
Gabby gets a message: "Islanders, tonight each couple will secretly vote for one other couple that they think should be dumped from the Island.
"You must now discuss in your couples who you’re going to choose and why, before submitting your decision by text.
"You must not discuss your decision with anyone else. The couples with the most votes face being dumped from the island. #thefinalcountdown”
Marcel reacts: “That’s the worst bombshell that has ever been dropped into this villa.”
Gabby adds: “Out of all the couples now there’s not one person who I want to go.”
The couples then talk about who they think should be dumped from the island.
"There relationship is genuine but I think she's just a little bit secure sometimes," Kem tells Amber.
"It's Love Island isn't it, they're not in love," Alex tells Montana.
"Can we literally mention this to no one?" Chris asks Olivia as they cast their vote.
With the final now in sight, some viewers fear the couples could be about to vote tactically.
One wrote to Twitter: "Got a really bad feeling they'll vote out Camilla and Jamie."
And a second added: "Some couples will vote Camilla and Jamie because they're threatened by them winning."
However the couples aren't deciding who goes - just which couples will be at risk of being dumped?
