Lauren was left sobbing after being blindsided by the twist - as Toni confessed they planned to recouple hours earlier on the terrace.
Lauren told the girls: "I am a f*****g idiot."
It all kicked off earlier when Billykiss received a text announcing: “Islanders, tonight there will be a recoupling in which the girls will choose which boy they want to recouple up with #NoMoreTriangles.”
Lauren told Harrison that she was nervous, but he reassured her: "She [Toni] won’t pick me."
Behind the scenes, Harrison had other plans.
He enlisted Harry to help sneak Toni up to the terrace for a heart-to-heart.
There he confessed: "I didn’t realise I liked you this much… I’ve been an idiot.
"At least you know how I feel now. Have a think.
"I understand I’ve been a bit of a d**k the last few days but I feel like I owed it to myself to explore. I just wanted to let you know how I feel — I still like you."
Toni didn’t hold back, replying: "But you like her too."
To which Harrison admitted: "Yeah… as hard as it is to believe I just want one girl."
Toni’s gave him a bold ultimatum and said: "She’ll still be here, she’ll still be around… it’s me or nothing."
She later made her move at the recoupling, and apologised to Cach and Lauren.
She said: "The last couple of days if not weeks have been really up and down and confusing.
"After a very unexpected conversation on the terrace this evening I've gotten the clarity and answers I've been looking for.
"I think this person has realised where they went wrong and hopefully things will work out from here on out. This decision has not been easy for me.
"I would like to apologise on behalf of both of us for the people we have hurt in coming to this decision."
Lauren - who was forced to chose Ty moments later - was visibly emotional.
Fans took to social media to brand Toni "desperate" as one said: "Toni is clearly not well. #Harrison has been toying with two desperate women."
Another said: "Na Toni this is desperate now!"
The other girls went one by one as Helena picked Harry, Meg chose Dejon, Shakira went for Conor, and Yasmin picked Jamie, calling him “the golden retriever to my black cat”.
Billykiss then chose Boris, Lauren picked Ty, and Emma picked a now-single Cach.
Toni had earlier told Cach she was removing herself from the triangle and deserved someone who put her first.
